With Jesus being fully man and fully God — while we can discuss the human part (like in this article) — it’s only the “God part” of Jesus (which has no measurement capabilities to it) — that makes Salvation at all possible and the “payment for sins” — efficacious.
I mean, the Bible says that a man can only die for one man’s sins — and so if Jesus was merely “man” who died and was raised from the dead, He could not pay for the sins of many.
It’s only because of His unlimited nature, as part of the Godhead, the Trinity — that makes this possible.
The “real part of Salvation” is the totally unseen part, in which He is part of the Godhead, the Trinity.
That’s understood. This article is about the physical suffering, though.
