Christ's crucifction

He wasn't sacrificed, though.
We can't even be sure if he actually felt any real pain, the whole thing could very well have been staged so Jesus could "die" at the right time, at the right place, under the right tear jerker circumstances, etc.

Could have gotten polio, letahl dysentery/cholera or stepped on a nail or gotten a heart attack from all the torture.

How anticlimactic would that have been?
Anyway, no reason why he wasn't just fortified by god to not feel any pain but still react as if he did, with screams and grunts, like an old man sitting down on a chair, "arggghhhhh".

It's just too convenient, reeks of the jewish mindset in storytelling.
Also I think Zig Forums is eating my post.

I mean he's taking on the sins of the world.

And?

Jesus was obviously terrified of what was about to happen when He prayed in Gethsemane. Jesus is fully human in addition to being fully God. Pain and death are just as real to Him as to any other man. His sacrifice was a death as brutal to Him as death is to any man, and a great deal worse than many deaths. He knew that He had the hope of the Resurrection to see Him through, but so does any believing Christian.

We admire Jesus not only as God, but also as the perfect human. His human aspect underwent the same difficulties we all do, the same temptations, and yet he gave into none. To have your flesh scourged off your bones and to be crucified even though you lived your while life without sin and in the service of others, that is the sacrifice of the Christ and it is matchless in history. Read the gospels and you will understand.

You're thinking to simply.

He symbolically became the paschal lamb and his death redeemed the sins of literally everyone. Then he went to hell and BTFO satan and released everyone from the bosom of abraham. Then he resurrected to establish his church and show us how he would return from the heavens.

Because he literally died for us willingly.
And no, being immortal doesn't invalidate this.

I mean his flesh is mortal but his soul is immortal just like the rest of us. On the 3rd day his flesh was resurrected with his soul inside it.

the incarnation itself was the sacrifice since the infinite God humbled himself and took up a human nature and all its limitations.
the crucifixion was simply accounted for and harmonized into the grand scheme of things, it wasn't something "necessary", there are no necessities for God since he is absolutely free and absolutely BASED
