"Yes, there are wrong ways to pray, but the most important part of prayer is actually praying. God loves it when we pray, because sincere, honest prayer in Jesus' name whos two of the most essential virtues in a Christian: humily and trust. When we ask God for help, we are saying, 'God, I cannot figure this out. I can't do it on my own. But You can help. You can change things. You can rescue me.' Mature Christian prayer always glorifies God becuase it is always humble and always confident. It beleives the battle is not ours but God's (2 Chron. 20:15)." Kevin DeYoung. The Good News We Almost Forgot. 239. 

Question 127: What does the sixth request mean? 

Answer: "And lead us not into temptation, but deliver us from the evil one" means, By ourselves we are too weak to hold our own even for a moment. And our sworn enemies - the devil, the world, and our own flesh - never stop attacking us. And so, Lord, uphold us and make us strong with the strength of Your Holy Spirit, so that we may not go down to defeat in this spiritual struggle, but may firmly resist our enemies until we finally win the complete victory.

Question 128: What does your conclusion to this prayer mean?

Answer: "For yours is the kingdom and the power and the glory forever" means, We have made all these requests of You because, as our all-powerful King, You not only want to, but are able to give us all that is good; and because Your holy name, and we ourselves, should receive all the praise, forever. 

Question 129: What does the little word "Amen" express?

Answer:"Amen" means, This is sure to be! It is even more sure that God listens to my prayer, than that I really desire what I pray for.
