How do we know that God's promises to Abraham are true?

God assured Abraham of His promises through a covenant, which is a solemn agreement that establishes the basis for God's relationship with humanity. In Genesis 15, God outlines specific promises to Abraham, including the assurance that he shall go to his fathers in peace, highlighting that God alone guarantees these promises. The reliability of God's covenants is affirmed through the entirety of Scripture as we see how God faithfully fulfills His promises to His people across generations, showing that they are not contingent on human actions but on His sovereign will and grace.
