God is to be trusted when his providences seem to run contrary to his promises. God promised to give David the crown, to make him king; but providence ran contrary to his promise. David was pursued by Saul, and was in danger of his life, but all this while it was David's duty to trust God. Pray observe, that the Lord by cross providences often brings to pass his promise. God promised Paul the lives of all that were with him in the ship; but the providence of God seemed to run quite contrary to his promise, for the winds blew, the ship split and broke in pieces. Thus God fulfilled his promise; upon the broken pieces of the ship they all came safe to shore. Trust God when providences seem to run quite contrary to promises.
