Then Simon Peter, who was behind him, arrived and went into the tomb. He saw the strips of linen lying there,
as well as the burial cloth that had been around Jesus’ head. The cloth was folded up by itself, separate from the linen.
Finally the other disciple, who had reached the tomb first, also went inside. He saw and believed.
(They still did not understand from Scripture that Jesus had to rise from the dead.) John 20:6-9

The last words we hear Jesus speak from the cross are "It is finished. Into your hands I commit my spirit." And he gave up his spirit and died.
Jesus had been able to say that the work God had given him to do was finished. And with that he surrenders his spirit into God's hands.

In the play we presented on Friday, I had Joseph of Aramathea wondering if everything that Jesus had taught and done was really finished. Was it really the end?  When Jesus was going to be arrested, Joseph had voted against it, but was over ruled. He was a follower but all he could do for Jesus was to loan him his own tomb and bury him with dignity. Was doing what was right and believing in God really nothing in the face of determined and powerful forces that were determined to obliterate it. On Friday, when Jesus died, it really seemed as if Judas, the high priests, Pilate and the rest had won. They succeeded in putting Jesus to death.

And in his own death, Jesus says, " It is finished."
Was it over?
In one way it was. Jesus earthly job was complete. His mortal body was dead. Dead and buried.
In that way, it was over.
In another way too.
He gave up the spirit. I re-read this passage to see if the gospels are speaking of his mortal spirit, or the Holy Spirit.
There is no indication. Just the words, "He gave up his spirit." I think we imply that he gave up both.

There is a very important statement which Jesus makes in John 8:28. "So then when you have lifted up the Son of Man, then you will know that I am the one I claim to be, and that I do nothing on my own, but speak just what the Father has shown me."
In one way he is saying that when they crucify him, they will see that he is telling the truth. How? Because he will not be kept in the grave. But it means more than just that. He is telling something about the work he came to do; the work he said "was finished". Here also what he says in John 5:30: "By myself I can do nothing; I judge only as I hear, and my judgment is just, for I seek not to please myself, but him who sent me."

Jesus says twice, "I do nothing on my own." In 5:30 he says "I can do nothing on my own."
When God became flesh in the person of Jesus, he lived a totally human life.
By that what I mean is he had no superpowers. I didn't have X-ray vision, or superhuman strength. He wasn't clairvoyant or any of that. He lived under exactly the same limitations that you and I do. Exactly.
Except that he is the Son of God. But don't make the mistake then of thinking he living in any way different from how you and I must. But what he had was the Holy Spirit and He was sinless. So he had total access to God's presence twenty four hours a day. Whatever he asked, God performed. It was the Holy Spirit's power, not the power of Jesus the man. This is important so stick with me.

Paul writes in Philippians :
Do nothing out of selfish ambition or vain conceit, but in humility consider others better than yourselves.
Your attitude should be the same as that of Christ Jesus:
