How is the Lord's prayer to be used?

The Lord’s prayer is not only for direction, as a pattern, according to which we are to make other prayers; but may also be used as a prayer, so that it be done with understanding, faith, reverence, and other graces necessary to the right performance of the duty of prayer.[1]

1. Matt. 6:9

   Pray then like this: “Our Father in heaven,
   hallowed be your name.

   Luke 11:2

   And he said to them, “When you pray, say:

   “Father, hallowed be your name.
   Your kingdom come.
