I have met people who have become wearied and disenchanted after spending years seeking an encounter or greater experience of God in their lives. They have gone to meetings, conferences, pilgrimages; they have read all the books; they have fasted and practised all the spiritual disciplines. But somehow they didn't find what they thought they we looking for. However, fellowship or communion with the Triune God is not something reserved for a spiritual elite; it's not a hidden secret, nor is it something in scarce supply. Rather here's a simple thought from C.S. Lewis about what is really happening when we bow our heads in prayer in our homes - calling on God as our Father, taking the posture as one of His children adopted in His Son, and brought near the heart of God by His Spirit - this is nothing less than participation in the inner triune life of God!
"An ordinary simple Christian kneels down to say his prayers. He is trying to get into touch with God. But if he is a Christian he knows that what is prompting him to pray is also God: God, so to speak, inside him. But he also knows that all his real knowledge of God comes through Christ, the Man who was God—that Christ is standing beside him, helping him to pray, praying for him. You see what is happening. God is the thing to which he is praying—the goal he is trying to reach. God is also the thing inside him which is pushing him on—the motive power. God is also the road or bridge along which he is being pushed to that goal. So that the whole threefold life of the three-personal Being is actually going on in that ordinary little bedroom where an ordinary man is saying his prayers. The man is being caught up into the higher kinds of life—what I called spiritual life - he is being pulled into God, by God, while still remaining himself."
