God could have let Abraham stay in the comfort of Ur in the Chaldees; He could have let Moses stay in the comfort of Pharaoh’s court, and Aaron stay in the safety of the crowd. He could have kept David away from Goliath; Shadrach, Meshach and Abednego out of the fiery furnace; Daniel out of the lion’s den; Elijah away from Jezebel; Nehemiah out of captivity; Jonah out of the whale; John the Baptist away from Herod; Esther from being threatened; Jeremiah from being rejected; and Paul from being shipwrecked. But he didn’t. In fact, God used each of these trials to bring people closer to himself, to produce perseverance, character and hope.
