How comforting it is to know that the Lord's Prayer covers every aspect of the Christian life! I have stated many times that if all we had was this small portion of the Bible as given from the lips of Jesus, we would have enough gospel to know how to be saved and how to live victoriously. This prayer includes every facet of a man's physical and spiritual life.
It's no surprise, then, that it includes the phrase "Lead us not into temptation." Jesus knew the difficulties we would face and the temptations that would lure every human being.
