Providence means God finely tuned the entire universe. He’s had the whole world in his hands from the very beginning. And providence means he’s still got the whole world in his hands, that nothing happens outside of his sight and outside of his governance. Just as all things are finely tuned in the universe, so is God even now finely tuning everything according to his plans. Joseph trusted in the providence of God, even when he could not see it. And ultimately, Joseph rejoiced in the providence of God, when God’s purposes were at last (partially) revealed.
