How do we know God will be faithful to His promises?

The assurance of God's faithfulness stems from His immutable character. As the Bible affirms, there is not even a shadow of turning in Him, which underpins our hope as an anchor for our souls. Throughout Scripture, we see His consistent fulfillment of promises, from the Old Testament to the New Testament. This faithfulness is ultimately demonstrated through Christ's redemptive work, wherein He loved His own unto the end, assuring us that He will continue to be with and uphold His people.
