Nowhere is the authority and power of God's Word stated more concisely, yet profoundly, than in the first chapter of Genesis: "And God said, Let there be light: and there was light." Gen. 1:3. In six other instances in this account of spiritual creation, God simply spoke "and it was so."
A record of the command of God's Word is not limited to this one chapter. Throughout the Bible we find spiritually-minded individuals employing the Word of God with awesome healing results. Those ancient healers who spoke God's Word expected results. One of them, John, tells us why. He writes, "In the beginning was the Word, and the Word was with God, and the Word was God." John 1:1.
If the Word is actually the living Principle and omnipotent Truth we call God, is it any wonder that a man crippled from birth was able to obey the Apostle Peter's God-impelled command to rise and walk? Should we think it incredulous that, at Christ Jesus' command, Lazarus, who had been buried for four days, responded by walking out of his tomb, alive?
