In this sermon, The Covenant, David Mulligan explores Genesis 12–22 to reveal the depth of God’s promises to Abraham and their fulfilment through Isaac. From Abraham and Sarah’s attempts to bring about God’s promises in their own strength, to the miraculous birth of Isaac as the true child of the covenant, the message highlights God as the provider and sustainer. Mulligan points to Isaac carrying the wood for sacrifice as a foreshadowing of Christ carrying the cross, showing how submission, love, and faith are central to God’s covenant relationship. The sermon calls believers to trust in God’s timing, rest in His promises, and live in the joy, peace, and revelation that His covenant love brings.
