The God Who Hears and Acts | Reflections on Genesis 21:1–21
This is from a sermon preached on Genesis 21:1-21.
Waiting is one of the hardest things we face in life. Whether it’s waiting for answers to prayer, clarity about the future, or resolution to a painful situation, it’s easy to grow anxious and doubt God’s timing. But Genesis 21:1–21 reminds us that God is faithful to His promises and that His timing is always perfect.
God’s Perfect Timing (Genesis 21:1–7)
After 25 years of waiting, Abraham and Sarah finally see God’s promise fulfilled with the birth of Isaac. God’s timing wasn’t just good—it was perfect. Isaac’s birth came when all human hope seemed lost, highlighting that God’s faithfulness doesn’t depend on human strength or understanding. For us, this means we can trust God even when the wait feels unbearable. His plans are always better than ours.
God Who Hears (Genesis 21:8–21)
The story also shows God’s compassion. When Hagar and Ishmael are sent away, God hears Ishmael’s cry in the wilderness and provides for them. This reveals God’s care for the vulnerable and His commitment to His promises. Even outside the covenant line, God remained faithful to His word to Abraham, making Ishmael a great nation. If God hears the cry of Ishmael, how much more can we trust Him to hear us when we call on Him in Christ?
Pointing to Jesus
Isaac’s miraculous birth points forward to Jesus, the ultimate fulfillment of God’s promises. Jesus is the true offspring of Abraham (Galatians 3:16), the mediator of the new covenant (Hebrews 9:15), and the one who brings salvation to all nations. Just as Isaac brought joy to Abraham and Sarah, Jesus brings eternal joy and hope to those who trust in Him.
What Does This Mean for Us?
For those who believe, this truth should bring great joy and peace. God’s timing may not match ours, but His faithfulness never wavers. While we wait, we’re called to trust, obey, and worship. Waiting is not passive—it’s an active expression of faith.
For those who haven’t trusted Christ, this passage invites you to consider the God who hears and acts. He offers salvation through Jesus, rescuing us from sin and judgment. Don’t wait—turn to Him today.
No matter what you’re facing, you can trust the God who hears and acts with perfect timing. His promises are sure, His timing is perfect, and His grace is sufficient. Will you rest in Him today?
