You may ask, ‘if we cannot imagine a three-personal Being, what is the good of talking about Him?’ Well, there isn’t any good taking about Him. The thing that matters is being actually drawn into that three-personal life, and that may begin any time – tonight, if you like.

What I mean is this. An ordinary simple Christian kneels down to say his prayers. He is trying to get in 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. Ye 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.
