The apostle John addresses a vital question: can someone truly encounter Jesus and remain unchanged? According to John, the answer is no—those who genuinely know Christ will walk in the light. That means acknowledging sin, not denying it, and trusting in Jesus as our advocate and atoning sacrifice. Confession is not a sign of failure but evidence of spiritual life. Through it, we are restored to fellowship with God and others. John's message assures believers that a changed life is not the root of salvation, but the fruit. This should lead to confidence in salvation and a desire to proclaim the gospel to a dark and broken world.
