Was It Sacrifice If Jesus Knew...?

Based on Matthew 27:46

How was Jesus' sacrifice a big deal since he knew he would be resurrected?

And about the ninth hour Jesus cried with a loud voice, saying, Eli, Eli, lama sabachthani? that is to say, My God, my God, why hast thou forsaken me? Matthew 27:46

Here Jesus is fulfilling/quoting Psalm 22:1.

My God, my God, why hast thou forsaken me? why art thou so far from helping me, and from the words of my roaring?

The psalm speaks of the feeling of abandonment and despair. It was soon after speaking these words that Jesus died, though not immediately. Jesus felt forsaken by God before his death, this was the ultimate pain for the one who had been perfectly united with the Father in eternity.

In Matthew 26:38 Jesus says:
My soul is exceeding sorrowful, even unto death
Jesus is full of pain and sorrow all ready, and he has not even begun to be crucified. Jesus is already suffering intense pain not from crucifixion but because the process of sin bearing is already beginning to be attributed to him.

In the next verse Jesus prays:
O my Father, if it be possible, let this cup pass from me: nevertheless not as I will, but as thou wilt.
This prayer is repeated later, demonstrating that to live a life of faith we must often commit our will and ways to the Father, not only once.

In verse 41 Jesus encourages his disciples to watch and pray so that they are not overcome by temptation. They do not watch and pray, and they are overcome by fear and confusion when Jesus refuses to resist arrest.

Be diligent and dependent on Jesus to overcome temptation and religious confusion, you can surrender your will to Jesus as often as you need to, this is the best place to start. Because Jesus went through the agony of losing his connection with the rest of the Godhead, but found it again by his divine power; he can reconnect you with God too. Jesus suffered temptation to doubt and compromise, he couldn't even be certain that he would rise from the dead. But he followed God's plan that the Holy Spirit impressed on him from the Bible, and he can give you everything you need to do the same.
