When Tim Keller was interviewed about his new book, Prayer: Experiencing Awe and Intimacy with God, here’s what he had to say about turning your theology into communion with God through biblical meditation and prayer:
Biblical meditation means, first, to think out your theology. (That means having it clearly in your mind. Know what you believe.) Second, it means to work in your theology. (That means self-communion, talking to yourself. For example, “Why are you cast down, O my soul?” It is asking yourself, “How would I be different if I took this theological truth seriously? How would it change my attitudes and actions if I really believed this from the bottom of my heart?”) Third, it means to pray up your theology. (That means turning your theology into prayer, letting it trigger adoration, confession, and supplication.) Do those things, and your theology will intersect with your experience….
It should go without saying—but I will say it—that what I mean by “meditation” is not any of the contemplative practices that aim at getting beyond words and rational thought into pure awareness of our oneness with God. Biblical meditation, rather, is filling the mind with Scripture and then “loading the heart” (to use John Owen’s phrase) with it until it affects not only the emotions but the entire life.
