"My attitude toward life was also my attitude toward science. Jesus said one must be born again, must become as a little child. He must let no laziness, no fear, no stubbornness keep him from his duty. If he were born again he would see life from such a plane he would have the energy not to be impeded in his duty by these various sidetrackers and inhibitions. My work, my life, must be in the spirit of a little child seeking only to know the truth and follow it. My purpose alone must be God's purpose - to increase the welfare and happiness of His people. Nature will not permit a vacuum. It will be filled with something. Human need is really a great spiritual vacuum which God seeks to fill... With one hand in the hand of a fellow man in need and the other in the hand of Christ, He could get across the vacuum and I became an agent. Then the passage, "I can do all things through Christ which strengtheneth me," came to have real meaning. As I worked on projects which fulfilled a real human need forces were working through me which amazed me. I would often go to sleep with an apparently insoluble problem. When I woke the answer was there. Why, then, should we who believe in Christ be so surprised at what God can do with a willing man in a laboratory? Some things must be baffling to the critic who has never been born again."
