Sirk,
Jesus was the perfect sacrifice body and soul.
Both His physical body and His Spirit are immortal.
Jesus would still be alive today if not for His sacrifice.
He was born of Mary and the Holy Spirit, perfect in every way, and in God's eyes.
Who could kill Him? Nobody.
Jesus GAVE up His physical body on the cross, still perfect, but carrying the "marks" of the sins of men on His body, and the sins of men on His soul.
His soul went to "paradise" , Lk 16:19-31,
Preached to those who were prisoners of sin until Jesus' sacrifice paid the price for sin. 1 Pet 3:19-20
When He rose from the dead, He brought with Him a "host of captives"(NAS), and "ascended up far above all heavens"(KJV).
His perfect body was in the grave until Jesus rose from paradise, where He took it up again.
This body was again, Mary and the Holy Spirit, God and Man.
