When God wants to do an impossible task, He takes an impossible man, and He crushes him.

From Acts 9:1-5:  “Meanwhile Saul, still breathing threats and murder against the disciples of the Lord, went to the high priest and asked him for letters to the synagogues at Damascus, so that if he found any who belonged to the Way, men or women, he might bring them bound to Jerusalem.  Now as he was going along and approaching Damascus, suddenly a light from heaven flashed around him.  He fell to the ground and heard a voice saying to him, ‘Saul, Saul, why do you persecute me?’  He asked, ‘Who are you, Lord?’  The reply came, ‘I am Jesus, whom you are persecuting.'”
