Donald Grey Barnhouse, former pastor of Tenth Presbyterian Church, made this powerful statement:
"Will God give man brains to see these things and will man then fail to exercise his will toward that God? The sorrowful answer is that both these things are true. God will give a man brains to smelt iron and make a hammer head and nails. God will grow a tree and give man strength to cut it down and brains to fashion a hammer handle from its wood. And when man has the hammer and the nails, God will put out His hand and let man drive nails through it and place Him on a cross in the supreme demonstration that men are without excuse."
