Well. The reason that Christ came. You do know what that is?
“IT” is the passover
Luke 22:15
And he said unto them, With desire I have desired to eat this passover with you before I suffer:
In this passover Christ makes the old covenant passover into the new covenant Passover (the last supper is the offertory) the New Testament in His blood. Luke 22:20
Likewise also the cup after supper, saying, This cup is the new testament in my blood, which is shed for you.
Christ is priest and victim:
1:29 The next day John seeth Jesus coming unto him, and saith, Behold the Lamb of God, which taketh away the sin of the world.
5 Your lamb shall be without blemish, a male of the first year: ye shall take it out from the sheep, or from the goats:
1 Peter 1:19
But with the precious blood of Christ, as of a lamb without blemish and without spot:
John 19:30
When Jesus therefore had received the vinegar, he said, It is finished: and he bowed his head, and gave up the ghost.
Christ is high priest heb 8:1
The high priest wears the seamless garment Jn 19:23-24
The words the high priest says at the consummation of the passover sacrifice: “it is finished”!
