Why is acknowledging our sinfulness important for Christians?

Acknowledging our sinfulness is crucial for Christians as it provides a proper understanding of our state before a holy God. Just as Naaman was a leper despite being a great man, we too are sinners by nature, unable to heal ourselves spiritually. Sin affects us inwardly, and Isaiah 1:6 illustrates that every part of us is corrupt without Christ. This recognition leads us to see our need for a Savior, reinforcing that salvation cannot be obtained through our efforts, but solely through Jesus Christ, who purged our sin by Himself, as stated in Hebrews 1:3. Embracing our need for grace allows us to appreciate the gift of salvation.
