THE WEAPON OF THE WORD
Luke 4:4, "And Jesus answered him, saying, It is written, That man shall not live by bread alone, but by every word of God."
MT. 4:1-11; MK. 1:12-13; LK. 4:1-13
Jesus answered every temptation with, "It is written." The Word of God is the sword of the Spirit (Eph. 6:17). It is the only offensive spiritual weapon that we have.
Since Jesus was the Word of God (Jn. 1:1), anything he would have spoken would have been the Word. He could have said "scat" and the devil would have had to go, yet He quoted the written Word of God three times.
This gives us great assurance that the written Word of God is sufficient for us. Jesus, in the face of the greatest temptations that Satan had to offer, did not need to say anything that was not already recorded in scripture.
It is likely that when Jesus returns to this earth and destroys His enemies, He will just speak the Word that has already been given in scripture. No wonder Satan tries to keep us from studying and knowing God's Word. Even our good works will hurt us if they keep us from really knowing the scriptures.
God has given us this mighty weapon of His Word! When we speak the Word in faith, hell shakes. Satan and his minions have already experienced what the Word can do. They know its power. We need to know it, too.
