What does the Bible say about God's faithfulness to forgive sins?

The Bible emphasizes that God's faithfulness to forgive is a reflection of His unchanging nature. In 1 John 1:9, it clearly states that if we confess our sins, He is faithful and just to forgive us. This highlights not only God's commitment to His promises but also His inherent justice, which requires the payment for our sins to be made. Thus, God forgives based on the completed work of Christ rather than our own merits or deeds. This assurance of salvation allows believers to confidently trust in His promises without fear of falling away due to their inadequacies.
