Prayer is communicating with God. When I need to communicate with my wife, we talk face to face, by phone, by video communication or text message. I am saying things to her and she replies through a variety of means. There are lots of methods to communicate with God. Indeed, in one way or another, all the disciplines are about communicating with God. We can train ourselves to carry on an almost constant conversation with God. This is the idea, I think, behind praying without ceasing. How glorious it is to realize, as C. S. Lewis taught, that I have God’s complete attention because God has unlimited attention! But the main thing to remember is to talk to Him. And listen. So, the Bible is an essential tool for prayer. The old Adoration, Confession, Thanksgiving and Supplication form is a great way to pray.
