How do we know God's covenant promises are secure?

In Exodus 33, God speaks to Moses about leading the stiff-necked people of Israel into the promised land, reaffirming His covenant made with Abraham, Isaac, and Jacob. Despite the people's sins, God remains committed to His promises, indicating that His divine purpose cannot be thwarted by human transgressions. The unchanging nature of God and His perfect faithfulness underpin the security of His covenant, emphasizing His intention to save sinners through Jesus Christ, the ultimate fulfillment of those promises.
