Supply and Demand: thinking about Good Friday

I have been noticing how much of life in this world consists of supply and demand.
It is the grandest fundamental of economics, and applicable to all aspects of life - neat little curves of give and take carving up my days and nights.
From buying a little toothbrush to having lunch with a friend to looking up the history of cupcakes on a search engine, every activity is saturated with supply and demand.
The funny thing is, no one likes to supply. That is, no one likes to supply without returns. Whether it's hard cold cash, a pat on the back, personal vendetta or being able to sleep at night, we want something back and consider it a grave injustice when the returns are a noshow or too meager for proper satisfaction. It makes me wonder if our acts of supply are really passive-aggressive acts of demand.
Today is Good Friday, and accordingly, I wondered about Jesus on the cross.
What was He thinking as He willingly gave Himself up to be crucified? Actually, what was He thinking as He willingly came from Heaven down to Earth? What gain did He have except to save our wretched souls? What gain does He, the great, magnificent and all-possessing creator, have from us? He has no demands that I could fulfill.
He is the great supplier because - well, because He is so great. The absence of demand removes all taint from His acts of supply. He has a supply curve that gives infinite quantity but demands no price from us. The price that should, accordingly, be infinity as the quantity is infinity, was paid in an infinite amount already around 2010 years ago on this very day.
What drives His supply is His neverending supply of love. Love compels Him.
Let me say that again - Love compels Him.
Love compels Him.
Love compels Him.
Love compels Him.
