What does the Bible say about God's covenant faithfulness?

The Bible consistently reveals God's steadfast faithfulness to His covenant. In the sermon, it is emphasized that even when Israel sinned and did evil in the sight of the Lord, God remained true to His promise. This faithfulness is a cornerstone of Reformed theology, illustrating that despite human sinfulness, God does not abandon His people. Romans 11:29 tells us, 'For the gifts and the calling of God are irrevocable,' highlighting that God's covenant is eternal and unbreakable, reassuring believers of His unchanging nature.
