Let us picture Jesus. He is on the mountain where Satan is tempting Him. He has been baptized and the Father has said He is pleased with His Son in Matthew 3:17, “And lo a voice from heaven saying, This is my beloved Son, in whom I am well pleased.”
Satan contests the declaration of the Father by tempting Jesus, who had not had food for forty day and nights. “But he answered and said, It is written, Man shall not live by bread alone, but by every word that proceedeth out of the mouth of God” (Matthew 4:4). Do you refer to the Scriptures precisely like Jesus did? I Peter 2:21 says, “For even hereunto were ye called: because Christ also suffered for us, leaving us an example, that ye should follow his steps.” Here is Jesus, God’s only begotten Son, and Deity at His weakest point in His humanity prior to Calvary. He says, “Man shall not live by bread alone, but by every word of God.” Bread was His greatest need at that moment. It was a necessity of life; yet Jesus said we shall live by every single word that comes out of God’s mouth. Measure faithfulness by every single word. It is written and it is still in force and stands today.
