oRead Acts 7:17-43. 7:17: "when the time of the promise drew near."

God is simply and supremely faithful.  He had promised Abraham (v5) a land after a period of bondage (v7).  The Egyptians would not stop God.  But neither would Moses.  At age 40 Moses went out in the flesh and botched any opportunity to lead Israel.  Most of us would have given up at that time, just as Moses did.  But not God, for God was now in a position to receive the glory for fulfilling the promise.  Ministry is like that.  It needs to fail until there is no room for our pride and only room for God's glory.
