How do we know that God forgives all our sins?

The assurance of God's forgiveness is explicitly stated in Psalm 103, where it declares, 'who forgiveth all thine iniquities.' This reflects the biblical truth that God's grace is sufficient and extends to covering all sins—past, present, and future. The context shows that the forgiveness we receive is not partial; it is comprehensive, affirming that through Christ's sacrifice, our transgressions are removed. This understanding leads to a heart of thanksgiving and worship, recognizing that our healing, spiritually and physically, comes from His cleansing power. Thus, believers can find true peace in knowing that their sins are fully forgiven.
