So it was that, when God destroyed the cities of the valley, God remembered Abraham and sent Lot out of the midst of the overthrow when he overthrew the cities in which Lot had lived. – Genesis 19:29
God will certainly give an answer of peace to the prayer of faith, in his own way and time; though, for a while, it seem to be forgotten, yet, sooner or later, it will appear to be remembered. The relations and friends of godly people fare the better for their interest in God and intercessions with him; it was out of respect to Abraham that Lot was rescued: perhaps this word encouraged Moses long afterwards to pray (Exodus 32:13), Lord, remember Abraham; and see Isaiah 63:11. Matthew Henry.
