Genesis 16:2

So Sarai said to Abram, “See now, the Lord has restrained me from bearing children. Please, go in to my maid; perhaps I shall obtain children by her.” And Abram heeded the voice of Sarai. (Genesis 16:2 NKJV)

Was Sarai correct in thinking that God restrained her? Does that automatically mean that God wanted to use someone else? Abram, instead of going to God, just heeded his wife. We need to go to God with our questions and wait on His answers. What do you need to trust God with in your life?
