If we serve God and Man as His servant people are bidden to do, then we are safe in His care. The answer is there in those lines, right beside the request. If the injury to us was deep and painful, it has brought us to our knees before God, and that is the best thing that ever happened to us. This makes it easier to forgive, because to feel God's love and mercy surrounding us is more than all else. And lead us not into temptation, but deliver us from evil.
Evil is a great big falsehood.
It promises all sorts of glittering rewards for disobedience to God and His Law. Its temptations are lies too, and the Christian follower of Jesus learns this by study of the Bible and by experience. Christians learn that the sinful world can give nothing of any lasting and permanent value. This prayer to be delivered from evil is really a prayer to be delivered from ignorance. Jesus tells us to seek first the Kingdom of God and His righteousness, and all these things will be added.
