Let us glorify the LORD for his wonderful work of giving Sarah a son. We’ll consider: 1. How Sarah laughed at the LORD’s promise. 2. How the LORD changed Sarah’s laughter into joy. 3. How we are to be filled with wonder at God’s great works. - Scripture Reading: Genesis 17:15-21; 18:1-15; 21:1-7, Text: Genesis 18:9-15
