If you’ve ever prayed for a friend, you should understand the Trinity. See, you stood in between God and your friend. And the three of you were one, the love of God binding you. See, God also stood between you two, loving you both. And if your friend was a mature believer, then the picture of the trinity is more perfect for you can be sure that at times your friend has also stood between you and God in his own prayers. So you three stood up for one another, each going to the other for his friend. This is the love of God in us.
