Why is it important for Christians to understand their spiritual sickness?

The acknowledgment of our spiritual sickness, as represented by the publican's cry, 'God be merciful to me, a sinner' (Luke 18:13), is central to Christian faith. This awareness is the first step toward genuine repentance and faith in Christ. Only when we see our need can we appreciate the fullness of Christ's redemptive work on our behalf. The ministry of Jesus is aimed at those who recognize their lost condition, revealing that the call to salvation extends to the humble and broken-hearted. This is an essential truth of the Gospel: our condition calls for a physician, and understanding this creates a deeper recognition of the grace offered to us in Christ, who heals our wounds and restores our lives.
