Introduction
† John continues speaking as a spiritual father to believers. His purpose isn't only to warn about sin, it's to reassure the church that forgiveness and life come through Jesus Christ. (1 John 1:7-9)
† At the same time he warns the church about deception that had already begun spreading among believers. False teachers were denying Christ and leading people away from the truth. (1 John 4:3)
† The chapter shows two clear paths, those who truly know God and walk in obedience, and those who claim to know Him but live in darkness. (John 13:34-35)

1 John 2:1
My children, I'm writing these things to you so you won't continue in sin. But if anyone does sin, we have someone who speaks on our behalf before the Father, Jesus Christ the righteous one.
† John isn't teaching sinless perfection, he's reminding believers that Christ stands as our advocate before the Father. (Romans 8:34)

This is how we know that we've truly come to know Him, if we keep what He commanded.
