1 John 5

1 John 5 explains the heart of true faith in Christ. It shows that those who truly believe in Jesus as the Christ and the Son of God are born of God. This faith is not just a belief in the mind, but a living faith that produces love, obedience, and victory over the world. John also teaches that God is the source of love and life, and that believers can have assurance of eternal life through His Son. This chapter gives confidence to believers, showing that they can know they have eternal life and can come to God in prayer with faith and assurance.

1 John 5:1-5 (NKJV)
1 Whoever believes that Jesus is the Christ is born of God, and everyone who loves Him who begot also loves him who is begotten of Him.
2 By this we know that we love the children of God, when we love God and keep His commandments.
3 For this is the love of God, that we keep His commandments. And His commandments are not burdensome.
4 For whatever is born of God overcomes the world. And this is the victory that has overcome the world—our faith.
5 Who is he who overcomes the world, but he who believes that Jesus is the Son of God?

This passage teaches that faith in Jesus as the Christ is the foundation of being born of God. A person who truly believes in Jesus will also love God and love those who are born of God, because all believers belong to the same spiritual family. John then explains that true love for God is not only a feeling or emotion; it is shown by keeping His commandments. God’s commandments are not meant to be a heavy burden, because when a person is born of God and lives by faith, obedience becomes the fruit of love. John also teaches that those who are born of God overcome the world, meaning they are given victory over sin, temptation, worldly desires, and spiritual deception. This victory does not come from human strength, but through faith in Christ, who is the Son of God and the One who overcame the world. True faith is active, not passive; it produces love, obedience, and an overcoming life with God.

1 John 5:6 (NKJV)
6 This is He who came by water and blood—Jesus Christ; not only by water, but by water and blood. And it is the Spirit who bears witness, because the Spirit is truth.

This verse teaches that Jesus Christ’s identity and mission are confirmed by “water and blood.” The “water” points to His baptism, where He was publicly revealed as the Son of God and began His ministry. The “blood” points to His sacrificial death on the cross, where His saving mission was completed. John says “not only by water, but by water and blood” because some false teachings may have accepted Jesus’ baptism or public ministry but denied the importance of His death. John makes it clear that the same Jesus who was baptized is also the One who truly died for humanity. His baptism and His death belong together and both witness to who He is. The Spirit also bears witness, because the Spirit is truth. The Spirit confirms the truth about Jesus through inner conviction, the testimony of Scripture, and the witness of the apostles. Together, the water, the blood, and the Spirit give a united testimony that Jesus is truly the Christ, the Son of God, and the Savior who came to give life.

1 John 5:7 (NKJV)
7 For there are three that bear witness in heaven: the Father, the Word, and the Holy Spirit; and these three are one.

This verse speaks of “three that bear witness” in heaven: the Father, the Word, and the Holy Spirit, and then says, “these three are one.” In the context of 1 John 5, the main subject is not explaining the nature or structure of God, but showing that there is a united testimony about Jesus Christ. John is speaking about witnesses that agree together concerning who Jesus is. Therefore, the phrase “these three are one” is best understood as meaning they are one in agreement, one in testimony, and one in purpose. They are perfectly united in bearing witness that Jesus is the Christ, the Son of God. It is also important to note that this specific wording is often called the Comma Johanneum, and it is widely recognized that it is not found in the earliest Greek manuscripts. It most likely entered the text later. But even without this added wording, the surrounding passage still teaches the same main idea: there are witnesses that agree together concerning Christ. In verses 6–8, John speaks of the Spirit, the water, and the blood bearing witness, and these three agree as one. So the emphasis of the passage is united testimony, not a philosophical definition of God as three persons in one being. For this reason, “these three are one” should not be used as the main foundation for the Trinity doctrine. In context, the unity being described is unity of witness and agreement. Just as the water, blood, and Spirit agree in their testimony about Christ, the Father, the Word, and the Spirit are also united in bearing witness to the Son. The point is that heaven’s testimony about Jesus is complete, harmonious, and true. Also, the Spirit “bearing witness” does not require the Spirit to be understood as a separate independent being equal to the Father. Rather, it shows that God’s own Spirit is the active divine testimony confirming the truth about His Son. The Father testifies of His Son, the Word is the Son Himself, and the Spirit brings that truth to the heart and confirms it in the believer. Therefore, the passage is best understood as teaching agreement in testimony about Christ, not as defining the Godhead in a Trinitarian or Tritheistic way.

1 John 5:8 (NKJV)
8 And there are three that bear witness on earth: the Spirit, the water, and the blood; and these three agree as one.

This verse explains that there are three witnesses on earth that testify about who Jesus is: the Spirit, the water, and the blood. These three do not give different messages; they agree together as one testimony. The Spirit is God’s divine witness, revealing Christ, convicting hearts, and confirming that Jesus is truly the Son of God. This witness was clearly seen at Jesus’ baptism, when the Spirit of God descended upon Him like a dove, and John the Baptist testified that Jesus is the Son of God. The water points to Jesus’ baptism, where His public ministry began and where He was openly revealed as the One sent by God. The blood points to His death on the cross, where He completed His mission, gave His life for humanity, and fulfilled the work of salvation. Together, the Spirit, the water, and the blood form a united testimony: the same Jesus who was baptized, anointed by the Spirit, and revealed as God’s Son is also the One who truly died for our sins. This means our faith in Christ is not based on empty claims, but on clear witnesses confirmed by God Himself.

1 John 5:9-10 (NKJV)
9 If we receive the witness of men, the witness of God is greater; for this is the witness of God which He has testified of His Son.
10 He who believes in the Son of God has the witness in himself; he who does not believe God has made Him a liar, because he has not believed the testimony that God has given of His Son.

John teaches that God’s testimony about His Son is greater than any human testimony. If people are willing to believe the witness of men, then they should even more believe the witness that God Himself has given about Jesus Christ. God has testified of His Son through the Spirit, the water, and the blood: the Spirit confirms the truth about Christ, the water points to His baptism, and the blood points to His sacrifice. Those who believe in the Son of God have this witness within themselves, meaning the Spirit confirms the truth of Christ in their hearts and lives. But those who reject God’s testimony are not simply rejecting an idea; they are treating God as a liar, because they refuse to believe what He has clearly revealed about His Son. This passage shows that faith in Christ is not optional or based on human opinion. It is the proper response to God’s own testimony, and rejecting that testimony has serious spiritual consequences.

1 John 5:11-13 (NKJV)
11 And this is the testimony: that God has given us eternal life, and this life is in His Son.
12 He who has the Son has life; he who does not have the Son of God does not have life.
13 These things I have written to you who believe in the name of the Son of God, that you may know that you have eternal life, and that you may continue to believe in the name of the Son of God.

John gives the central message of God’s testimony: God has given us eternal life, and this life is found in His Son. Eternal life is not something we earn by our own works; it is a gift from God through Jesus Christ. To have the Son means to have life, because the life of God is given to us in Christ. But whoever does not have the Son does not have this life, because eternal life cannot be separated from Jesus. John writes these things so believers may know that they have eternal life, not merely hope or guess. This assurance is meant to strengthen their faith and encourage them to continue believing in the name of the Son of God. True confidence in salvation comes from having Christ and continuing in faith in Him.

1 John 5:14-15 (NKJV)
14 Now this is the confidence that we have in Him, that if we ask anything according to His will, He hears us.
15 And if we know that He hears us, whatever we ask, we know that we have the petitions that we have asked of Him.

John teaches that believers can have confidence when they come to God in prayer. This confidence is not based on demanding whatever we want, but on asking according to God’s will. When our prayers are in harmony with His will, we can know that He hears us. And if we know that He hears us, we can trust that He will answer in the right way and at the right time. This does not mean God gives every selfish desire, but that He faithfully responds to prayers that agree with His purpose, wisdom, and love. Prayer is therefore an expression of trust and relationship with God. Believers can come to Him with assurance, knowing that He listens to His children and grants what is truly good according to His will.

1 John 5:16-17 (NKJV)
16 If anyone sees his brother sinning a sin which does not lead to death, he will ask, and He will give him life for those who commit sin not leading to death. There is sin leading to death; I do not say that he should pray about that.
17 All unrighteousness is sin, and there is sin not leading to death.

John teaches believers to pray for a brother who falls into sin, especially when that sin is not leading to death. This means there are sins that are serious but still open to repentance, forgiveness, and restoration. When we see a fellow believer struggling or falling, our first response should not be gossip, judgment, or rejection, but intercessory prayer, asking God to restore life to that person. However, John also speaks of sin leading to death, which likely refers to a hardened, willful, and persistent rejection of God’s truth and Spirit, similar to the warning about blasphemy against the Holy Spirit. In such a case, the issue is not that God is unwilling to forgive, but that the person has become resistant to repentance and refuses the only means of life. John then reminds us that all unrighteousness is sin, so no sin should be treated lightly. Yet not every sin immediately means final separation from God. This passage teaches both mercy and seriousness: we should pray for those who fall, but also recognize the danger of deliberate rebellion against God.

1 John 5:18-19 (NKJV)
18 We know that whoever is born of God does not sin; but he who has been born of God keeps himself, and the wicked one does not touch him.
19 We know that we are of God, and the whole world lies under the sway of the wicked one.

John contrasts those who are born of God with the world that lies under the power of the wicked one. When he says that whoever is born of God does not sin, he does not mean that believers never make mistakes or never fall. He means that those who are truly born of God do not continue living in willful, habitual, and unrepentant sin as their way of life. The one born of God keeps himself by remaining in faith, obedience, and dependence on Christ, and the wicked one cannot take control of him. This is because God protects and keeps His children through His life and grace. Verse 19 reminds us that believers belong to God, but the world is under the influence of Satan, filled with sin, deception, and spiritual darkness. This passage gives assurance that those who are born of God are no longer under Satan’s dominion, but are kept by God and separated from the spirit of the world.

1 John 5:20 (NIV)
“We know also that the Son of God has come and has given us understanding, so that we may know Him who is true. And we are in Him who is true by being in His Son Jesus Christ. He is the true God and eternal life.”

This verse affirms that Jesus Christ, the Son of God, has come to give us understanding so that we may know “Him who is true” — that is, God the Father. The NIV makes the flow clearer by saying, “we are in Him who is true by being in His Son Jesus Christ.” In other words, believers are in the true God, the Father, through His Son, Jesus Christ. Some argue that the final phrase, “He is the true God and eternal life,” must refer to Jesus because Jesus is mentioned immediately before it. However, the Bible does not always follow the nearest-antecedent rule; context must determine the meaning. The context points back to “Him who is true,” the Father, whom Jesus also identified in John 17:3 as “the only true God.” Therefore, 1 John 5:20 should not be used to contradict John 17:3. Rather, it teaches that the Son came to reveal the true God, and that we come to know and abide in the Father through His Son. Jesus is the divine Son through whom eternal life is revealed and given, while the Father remains the true God and source of eternal life.

1 John 5:21 (NKJV)
21 Little children, keep yourselves from idols. Amen.

In the context of the previous verse, where God the Father is identified as the true God, John’s warning reminds believers to stay away from every false representation of God and remain faithful to Him as revealed through Jesus Christ. Idolatry is not only worshiping physical idols made of wood, stone, or metal. It can also include false ideas, false doctrines, or distorted views of God that replace the truth revealed in Scripture. One example is the Trinity doctrine, which can misrepresent God by presenting Him as a three-in-one being, instead of keeping the biblical distinction between the Father as the one true God and Jesus Christ as His Son, as Jesus Himself taught in John 17:3. When people worship a concept of God that is shaped more by human tradition than by Scripture, it can become a form of spiritual idolatry, because it replaces the true knowledge of God with a man-made understanding. John’s warning also applies to anything else that takes God’s rightful place in the heart, whether false teachings, material possessions, worldly desires, pride, or self-exaltation. Believers are therefore called to keep themselves from idols by remaining in the truth, abiding in Christ, and worshiping the one true God as revealed through His Son.
