How and what to Pray:
Although we might see or hear people praying all sorts of prayers to all kinds of gods, some of whom they at least think they know better than others, Christian prayer is unique. It reflects our unique knowledge of and trust in the one true God, Father, Son and Holy Spirit, who has created all things, redeemed us by His blood and sanctified us in His holy Church. We pray from a position of confidence, sure that God will hear us and grant us what is good because we pray by Christ’s command, according to His promise and even according to His explicit instructions. Yet how we have often rushed through those words, “Our Father . . .,” without thinking what a remarkable gift it is that Christ would have us pray this way.
After all, for Luther, as with Baptism and the Lord’s Supper, the right place to begin to answer the question “What is prayer?” and “How shall we pray?” and the like is with our Lord’s own command and promise. For when His disciples asked Him how they should pray, the Lord said, “When you pray, say . . . .” And then He gave them what we call the Lord’s Prayer. Here is where Christians, with the disciples, learn to pray, by the Holy Spirit. How does He teach? By the words of God: the Psalms, Gospels and Epistles, the whole Scripture, but especially “the very best prayer, because the true master of prayer, Jesus, composed it and taught it to us.”

Lord's Prayer from Matthew:
Matthew 6:9-13 New International Version (NIV)
9 “This, then, is how you should pray:
“‘Our Father in heaven,
hallowed be your name,
10 your kingdom come,
your will be done,
on earth as it is in heaven.
11 Give us today our daily bread.
12 And forgive us our debts,
as we also have forgiven our debtors.
13 And lead us not into temptation,
but deliver us from the evil one.
