David was thirty years old when he became king, and ruled for forty years. In Hebron he ruled Judah for seven and a half years. In Jerusalem he ruled all Israel and Judah for thirty-three years. 2 Samuel 5:4-5

There is so much waiting in scripture! Joseph, Jesus, Paul, Moses, Noah, Hannah, Nehemiah, Esther, Sarah, Jeremiah, the list goes on and on. 

Why does God call us and then make us wait?
