What does a truly Christian life look like? In this message from 1 John 2:1–14, we explore the second mark of true Christianity: a life marked by holiness. John shows us that while Christians are not sinless, they are no longer characterized by sin. True faith produces obedience, love for others, and a growing likeness to Christ.At the same time, this passage offers deep hope. When we do sin, we are not left in despair—Jesus is our righteous Advocate and the atoning sacrifice for our sins. Through Him, both the penalty and power of sin are overcome.
