“Since prayer is talking with God, why don’t people pray more? Why don’t the people of God enjoy prayer more? I maintain that people—truly born-again, genuinely Christian people—often do not pray simply because they do not feel like it. And the reason they don’t feel like praying is that when they do pray, they tend to say the same old things about the same old things.”
That’s from page 11 in this book:
Donald S. Whitney. Praying the Bible. Wheaton, IL: Crossway, 2015.
In Praying the Bible, Whitney says more winsomely and practically what I argue for in this essay:
Andrew David Naselli. “12 Reasons You Should Pray Scripture.” Themelios 38 (2013): 417–25.
