Discipleship does not begin with self-improvement, moral effort, or religious sincerity—it begins with new birth. Jesus confronts Nicodemus with the truth that spiritual life cannot be achieved, inherited, or engineered. Apart from the Spirit’s work, we are spiritually dead, even when we appear religious, busy, or sincere. A clear view of who we are apart from Christ exposes our need for rescue and reorients us to the One who alone gives life. The Gospel is not advice for the alive; it is resurrection for the dead.
