How do we know that God forgives us when we repent?

In the account of the Prodigal Son, we see a vivid portrayal of God's forgiveness towards sinners who genuinely repent. The son acknowledges his sin, declaring, 'I have sinned against heaven and before you' (Luke 15:18). This acknowledgment is the first step toward restoration and highlights the principle that God forgives those who come to Him with a contrite heart. The father's reaction—celebrating the son's return—underscores the truth found throughout Scripture that God delights in forgiving those who turn back to Him. Passages like 1 John 1:9 assure us that if we confess our sins, He is faithful and just to forgive us. Thus, we can be confident in God's promise of mercy for all who seek His forgiveness.
