How do we know we are sinners before God?

The acknowledgment of sin is an important aspect of Christian faith, as seen in David's confession in Psalm 51. He recognizes his transgressions, stating, 'Against thee, thee only, have I sinned.' This admission reflects a heart attuned to the gravity of sin against God. Each believer is made aware of their sinfulness not only through conscience but by the Holy Spirit's conviction, who reveals the truth of our depravity and need for God's grace. Romans 3:23 tells us that all have sinned and fall short of the glory of God, emphasizing the universal nature of sin and our need for repentance.
