ok but Jesus was actually crucified when ?
33 ad. But in Gods estimation, who is Eternal, and not confined to time, He was slain from the foundation of the world Rev 13:8. So He viewed Christ already slain in Jn 8 24.
OT Prohecy had Him already slain for sins Isa 53:
All we like sheep have gone astray;
we have turned every one to his own way;
and the Lord hath laid on him the iniquity of us all.
7 He was oppressed, and he was afflicted,
yet he opened not his mouth:
he is brought as a lamb to the slaughter,
and as a sheep before her shearers is dumb,
so he openeth not his mouth.
8 He was taken from prison and from judgment:
and who shall declare his generation?
for he was cut off out of the land of the living:
for the transgression of my people was he stricken.
