Isn't it amazing how the Psalmist in chapter 119 refers so much to what God's Word does for him? Over and over again, he trusts in the precepts and commandments of God. Not because those etched words have power, but because the author of those words give power to them.
How did Jesus handle Satan's temptations in the wilderness? "It is written." Jesus quoted the Word, yet He Himself, was the Word. "In the beginning was the Word and the Word was with God and the Word was God." John 1:1. Perhaps that is why it behooves us to memorize and speak those same Words. For in them, and through them are the power of God to use as a sword to open the hearts of men and provide entrance for the faith and grace of God. selahV
