In this episode of the Know Your Bible Program, host David J. Lewis walks us through Genesis 21–24 to explore the life of Isaac, the long-awaited son of promise. From God fulfilling His word to Abraham to the prophetic parallels hidden within the sacrifice on Mount Moriah, this study reveals how God's timeline always unfolds with purpose—and how Isaac's story points directly to Jesus Christ.
