Christ is immortal unable to become unconscious in sleep or die.
God does not sleep.
Psalms 121:
2 My help cometh from the LORD, which made heaven and earth.
3 He will not suffer thy foot to be moved: he that keepeth thee will not slumber.
4 Behold, he that keepeth Israel shall neither slumber nor sleep.
1st Timothy 6;
14 That thou keep this commandment without spot, unrebukeable, until the appearing of our Lord Jesus Christ:
15 Which in his times he shall shew, who is the blessed and only Potentate, the King of kings, and Lord of lords;
16 Who only hath immortality, dwelling in the light which no man can approach unto; whom no man hath seen, nor can see: to whom be honour and power everlasting. Amen.
Jesus was back then mortal, and did sleep.
Matthew 8:
22 But Jesus said unto him, Follow me; and let the dead bury their dead.
23 ¶ And when he was entered into a ship, his disciples followed him.
24 And, behold, there arose a great tempest in the sea, insomuch that the ship was covered with the waves: but he was asleep.
25 And his disciples came to him, and awoke him, saying, Lord, save us: we perish.
26 And he saith unto them, Why are ye fearful, O ye of little faith? Then he arose, and rebuked the winds and the sea; and there was a great calm.
Mark 4:
37 And there arose a great storm of wind, and the waves beat into the ship, so that it was now full.
38 And he was in the hinder part of the ship, asleep on a pillow: and they awake him, and say unto him, Master, carest thou not that we perish?
39 And he arose, and rebuked the wind, and said unto the sea, Peace, be still. And the wind ceased, and there was a great calm.
Hebrews 2:9 But we see Jesus, who was made a little lower than the angels for the suffering of death, crowned with glory and honour; that he by the grace of God should taste death for every man.
Dead humans are called corpses. The eternally living Christ was welded inside the corpse of Jesus. Things must move at a schedule to fulfill Scripture. No corruption allowed.
Revelation 1:18 I am he that liveth, and was dead; and, behold, I am alive for evermore, Amen; and have the keys of hell and of death.
Revelation 2:8 And unto the angel of the church in Smyrna write; These things saith the first and the last, which was dead, and is alive;
Hebrews 2:14 Forasmuch then as the children are partakers of flesh and blood, he also himself likewise took part of the same; that through death he might destroy him that had the power of death, that is, the devil;
