Promise in the Midst of Dysfunction

Genesis is foundational to christians theology because it shows us how God works: how He keeps promises, how He moves through families, and how His purposes unfold across history. In Genesis 21 we see both joy and heartbreak. Isaac is born just as God promised. After decades of waiting, “The Lord did to Sarah as He had promised.” Our God is a promise-keeping God.

Yet the same chapter reveals deep family dysfunction. Ishmael and Hagar are sent away. What began years earlier through human impatience now fractures a household. The ripple effects of this family divide still shape world history today. Genesis is honest: sin complicates families, favoritism wounds children, and our attempts to “help” God often create pain.

But there is mercy, God does not abandon the broken. He hears the cry of Ishmael in the wilderness. He provides water. He keeps His word to Abraham. God’s purposes are not undone by human failure.

Genesis 21 reminds us that dysfunction does not get the final word, God does. His grace works through messy stories and divided homes. And ultimately, through Isaac’s line, God brings Jesus who is the true Son of promise and he carries our sin and secures our salvation.

When families fail and the world feels fractured, we cling to this: the Lord keeps His promises.
