The two are so close that the Son is “in the bosom of the Father”—that is, resting his head on his chest, as close friends did while reclining on carpets around a low dinner table in the Middle East (John 1:18 Kjv). Furthermore, God has taken the universe and turned the shop over to the Son: “All things have been committed to me by my Father” (Luke 10:22).
Why does the Father treasure him so? Because he sees himself in his Son. His own perfections are flawlessly reflected there. The Son is God standing in the mirror. In him God sees the fountain of all the intelligence, grandeur, and goodness that ever was. We look in the mirror and are almost always disappointed. God looks in the mirror and is riveted. To put it almost ridiculously, if the Father ever had any “cravings” they are more than met by the Son. The eternal Threesome revels together in a swirling dance of mutual love. The Trinity enjoys pleasure beyond comprehension.
