I’ll admit scripture memorization hasn’t been my thing. In Donald Whitney’s book Spiritual Disciplines for the Christian Life he brings up how Jesus was able to stand the temptations of the devil by quoting Scripture. What he didn’t mention though was all the scripture Jesus quoted was from Deuteronomy. Think Deuteronomy is an old boring book of the Old Testament? Apparently there’s enough there to ward of the devil! Maybe you should reconsider reading it?
