This entire section of scripture (Genesis 21:1-8) is one of the most encouraging, excitable, and reassuring passages you can find. It declares with a mighty voice, “God Keeps His Promises!”
In the life and pilgrimage of Abraham and Sarah, this day is a day like no other they had experienced and shared. As God had promised, “It’s a Boy!” Twenty-five long years of waiting, sometimes running ahead of God, sometimes failing to trust God, but never, ever, not once, being forsaken or forgotten by God! And now, here is a passage dripping with joy and gratitude!
God is Faithful. We all know what it is like to experience a broken promise, but there is One who is true! There is One who will never leave you, nor forsake you (Hebrews 13:5)! There is One who has said, “I have loved you with an everlasting love” (Jer. 31:3), and you can trust Him!
