1 John 2:1-3 restates John’s purposes for writing this letter: that we may not sin. He explains that if we do sin, Jesus is both our advocate and propitiation, which means that He has turned away God’s wrath and petitions for forgiveness on our behalf. Avoiding sin allows us to know God, obey His commandments, and experience the fullness of eternal life.

1 John 2:4-6 teaches that anyone who claims to know Christ yet does not keep His commandments is not living in the truth, but is a liar and a hypocrite. In contrast, the one who keeps His word demonstrates that the love of God has reached its intended maturity in him. The evidence of truly abiding in Christ is walking in the same pattern of obedient dependence that Jesus Himself walked.

1 John 2:7-8 reminds John’s readers that the command to love one another is not a recent innovation but something they have known from the beginning of their faith. Yet it is also new in the sense that it has been fully revealed and embodied in Jesus Christ and is now being expressed in and through those who walk in Him. This command reflects the reality that the darkness is passing away and the true Light is already shining.
