I think humans were the one who came in with the concept that something has more validity to it if more numbers are involved, and the less numbers involved, the less significant it is. Love is qualified, it is not quantified, and God is love.
He endured the Cross for the joy set before Him (Heb 12.2) and here's one more thing to think about with this whole transaction here; since you're the only
sinner, that also means that you personally would be tacking Him to that Cross-- make it a little harder to look Him in the eye when it was all said and done. And yet Jesus would still endure this.
