Q. 98. What is prayer?
A. Prayer is an offering up of our desires unto God, for things agreeable to his will, in the name of Christ, with confession of our sins, and thankful acknowledgement of his mercies.Keller notes that the catechism's answer indicates that we should ask God to fulfill desires, even though we may be plagued with sinful or well-intentioned but mistaken desires. Keller then looks to J. I. Packer for wisdom on how to proceed with asking God for things in light of the dangers brought to light in the catechism.
First, Keller argues that we should embed "theological reasoning in all our prayers." He quotes Packer, "we should lay before God, as part of our prayer, the reasons why we think that what we ask for is the best thing" and "why what we have asked for seems to us to be for the best, in light of what we know God;s own goals to be." This is a very helpful suggestion. This embedding of theological reasoning will be a safeguard if we find ourselves with desires that don't align with God.
Second, Keller informs us of Packer's instruction to tell God in our prayers "that if he wills something different we know it will be better and it is that (rather than the best we could think of) that we really want him to do." This, again, is very helpful for maintaining a reverent attitude while we petition God for our desires. Quoting Packer, Keller writes, "We must ask ourselves "what we ourselves might need to do to implement answers to our prayers."" Keller continues, "To some degree, the answers to many of our petitions would be facilitated by changes in us, but we usually do not take time to consider this as we pray." This final insight impacted me the most; I don't think I even consider this approach.
Asking God for things in prayer is not only a privilege, it's a command. But we petition God best when we do it intelligently, reverently, and with self-reflection.
