Catechesis: Introduction to Lord’s Prayer

Nothing is more necessary than that we should continually turn towards God’s ear, call upon Him, and pray to Him. We must pray that He would give, preserve, and increase faith in us and fulfillment of the Ten Commandments.—LC III:2

And the first thing to know is that it our duty to pray because of God’s commandment.—LC III:5

Praying, as the Second Commandment teaches, is to call upon God in every need. He requires this of us and has not left it to our choice. But it is our duty and obligation to pray.—LC III:8

I rest my prayer on the same commandment on which all the saints rest their prayer. Furthermore, I pray for the same thing that they all prayed for and always have prayed.—LC III:16
