First John 2:3 says that we can know we truly know God by whether we keep his commands. Obedience is the evidence of a real relationship, not a ladder we climb to earn one. The verse was written by the apostle John, traditionally identified as the disciple who wrote the Gospel and Revelation, to a community of believers he calls “little children” and who needed clarity about what genuine faith looks like.
This is how we know that we know him: if we keep his commandments.

What 1 John 2:3 Means
The verse opens with “This is how we know,” which signals a test rather than a theory. John is not saying that a person must first obey before God accepts them. He is giving a way to check the claim “I know God.” If someone says they have a relationship with God but their life shows no willingness to follow what God asks, the claim is in doubt. The knowing John describes is personal and relational, the kind you have with a close friend, not a mere grasp of facts.
The phrase “if we keep his commandments” carries weight in that test. To keep means to hold onto, guard, and live out. The commands in view are not a long list of rules but the shape of God’s will, most clearly summed up later in the letter as trusting Jesus and loving one another. The verse does not promise perfection. John admits in the surrounding chapter that believers still sin, which is why he points to Jesus as the one who speaks for us with the Father. What the verse does promise is that a steady direction of life toward God’s ways is the mark of someone who truly knows him.
The Context of 1 John 2:3
First John is a letter, not a narrative, written to churches facing the pressure of false teachers who claimed special spiritual insight while living in ways that contradicted the gospel. Some had apparently left the community and insisted they had moved beyond ordinary Christian morality. John addresses those claims directly, giving believers tests they can apply to what people say about themselves and about God.
Just before verse 3, John reminds his readers that Jesus is the atoning sacrifice for sins, and just after it, he warns that anyone who says “I know him” yet refuses to keep his commandments is a liar. Read in that frame, verse 3 is not a standalone rule about earning God’s favor. It is the first of several tests John offers, each one showing that real faith is visible in real life. Seeing that flow helps readers avoid turning the verse into a source of anxiety and instead read it as an invitation to examine whether their daily choices match what they profess.
Key Phrases in 1 John 2:3
John 14:15
If you love me, keep my commandments.

Jesus links love for him directly to keeping his commandments, which helps explain why John treats obedience as the evidence of knowing God. Reading the two together shows that the test in First John grows out of the relationship Jesus himself describes.
1 John 4:7-8
7 Beloved, let us love one another, for love is of God; and everyone who loves has been born of God, and knows God. 8 He who doesn’t love doesn’t know God, for God is love.

Later in the same letter, John ties knowing God to love, saying that whoever loves has been born of God and knows him. This passage fills out the meaning of keeping his commandments by showing that love is the heart of what God asks and the clearest sign of a genuine relationship with him.
A Short Prayer From 1 John 2:3
Father, you have made yourself known to us through your Son, and I want my life to show that I truly belong to you. Search my heart where I have said I know you but my choices tell another story. Give me the grace to keep your commands out of love rather than fear, and forgive me where I have fallen short. Thank you that you meet me in my weakness and that Jesus speaks for me before you. Shape my everyday decisions so that my life quietly reflects the reality of knowing you. Amen.
