Why a theology of prayer? Because counterfeit prayer abounds, we need Scripture's guidance, writes Thomas Constable. Praying as God desires requires considering what God has revealed about it. As we give prayer our careful attention, we gain greater understanding of what he intends it to be. Constable details the different forms of communication God invites us to use. He identifies the counterfeits that pass for prayer, discusses the conditional nature of prayer, and explains why some prayers seem to go unanswered.
