Have you ever felt a prompting to do something that seemed so impossible, you could only shake your head in disbelief? But then somehow, God intervened and everything turned out better than you could have imagined? We read about Sarah experiencing those same feelings when the Lord tells her she is going to have a son way past her childbearing years. This week, we'll dig into Genesis chapters 18–23 and learn from the stories of Abraham, Sarah, and Isaac about how nothing is too hard for the Lord—and how our disbelief can be turned into rejoicing.
