Stretching out one's hand for the stone is an act of faith. This would be exercised by a man who believes that God can use mean things to bring down the haughty and the mighty. Our stone may be as insignificant as Moses' rod, Jehoshaphat's trumpet, footnoise of the 4 lepers, and/or as simple as the Cross. If we pick up the stone, no giant can stand the way. Thanks @Darlenys01 for this morning booster.
