The study group I attend has been reading the Gospel of John. We just finished John chapter 12 and these questions came up.
If Jesus wasn’t killed by those who opposed him, would he have lived forever on the earth among his people?
Being without sin he would never die, But there is no hypothetical in scripture, he was the Lamb Slain before the world.
If Jesus would have died a natural death would it have satisfied God?
Again , no Hypothetical, but no it would not. PSA is the biblical teaching ; Hebrews 9 and 10 are more than conclusive;
12 Neither by the blood of goats and calves, but by his own blood he entered in once into the holy place, having obtained eternal redemption for us.
14 How much more shall
the blood of Christ, who through the eternal Spirit offered himself without spot to God, purge your conscience from dead works to serve the living God?
15 And for this cause he is the mediator of the new testament, that
by means of death, for the redemption of the transgressions that were under the first testament, they which are called might receive the promise of eternal inheritance.
22 And almost all things are by the law
purged with blood; and without shedding of blood is no remission.
23 It was therefore necessary that the patterns of things in the heavens should be purified with these; but the heavenly things themselves with better sacrifices than these.
26 For then must he often have suffered since the foundation of the world: but now once in the end of the world hath he appeared
to put away sin by the sacrifice of himself.
jn1:29 The next day John seeth Jesus coming unto him, and saith, Behold the Lamb of God, which taketh away the sin of the world.
