"There is such a thing as correspondence with heaven, and prayer is a great part of it while we dwell on earth." p. 169
Excellent little book which opened my eyes to depth of rich conversation that I can have with God. I finished the book, feeling challenged yet with a clear idea of what aspects I could incorporate in prayer.
The first chapter, "The Nature of Prayer," which was particularly profitable, explained the parts of prayer. Pleading with God, arguing our case with him in a fervent yet humble manner, was something that I would initially think presumptuous. Yet we see this kind of conversing in Scripture. We may plead by the perfection of the nature of God (his mercies' sake), by His relations to men (Creator), by promises of the covenant of grace, by the name and honor of God in the world, former experiences of ourselves and others. The most important is to plead by the name and mediation of Christ.
I was also encouraged by Watts' chapter on how the Spirit assists us in prayer - He gives us natural capacities of understanding, memory, and intelligence; He blesses our diligent reading, hearing, meditation; He inclines our heart to prayer. . . I appreciate that Watts makes an effort to find a balance between attributing too much or too little to the Holy Spirit.
Men must toil to acquire knowledge in a certain field. Similarly, prayer does not come without diligence, but we have the Holy Spirit's assistance! To develop skill in prayer, Watts recommends drawing up a prayer to use monthly, yet giving oneself liberty to enlarge, as one feels led.
