Chapter 23 — Part II — The Lord's Prayer
Section 432. Q. Why after the Lord's Prayer do we subjoin the Doxology? A. First, that when we ask mercies for ourselves from our heavenly Father, we may at the same time render him that honor which is his due; secondly, that by the thought of his everlasting kingdom, power, and glory, we may be more and more established in the hope that he will give us what we ask, because this is in his power, and makes to his glory.
