Luke 23:50 And, behold, there was a man named Joseph, a counsellor; and he was a good man, and a just:
Joseph was a member of the Sanhedrin council, he is described as a good righteous man. Righteousness comes by faith in the promised redeemer.
Luke 23:51 (The same had not consented to the counsel and deed of them;) he was of Arimathaea, a city of the Jews: who also himself waited for the kingdom of God.
He was not with the council in their complete agreement to kill Jesus. He believed in and anticipated the coming kingdom of God.
Luke 23:52 This man went unto Pilate, and begged the body of Jesus.
He asked for the body of Jesus, the Spirit had returned to the Father.
Luke 23:46 And when Jesus had cried with a loud voice, he said, Father, into thy hands I commend my spirit: and having said thus, he gave up the ghost.
He descended in spirit to paradise releasing some or all the old testament saints who trusted in his coming. Those of old who were righteous went to paradise and those not of faith were in hell.
Eph 4:8 Wherefore he saith, When he ascended up on high, he led captivity captive, and gave gifts unto men.
Eph 4:9 (Now that he ascended, what is it but that he also descended first into the lower parts of the earth?
Eph 4:10 He that descended is the same also that ascended up far above all heavens, that he might fill all things.)
The good news is when we die believing in Jesus, we go to him.
2 Cor 5:8 We are confident, I say, and willing rather to be absent from the body, and to be present with the Lord.
Phil 1:21 For to me to live is Christ, and to die is gain.
Phil 1:22 But if I live in the flesh, this is the fruit of my labour: yet what I shall choose I wot not.
Phil 1:23 For I am in a strait betwixt two, having a desire to depart, and to be with Christ; which is far better:
Joseph prepared the body for burial
Luke 23:53 And he took it down, and wrapped it in linen, and laid it in a sepulchre that was hewn in stone, wherein never man before was laid.
This was a fulfillment of a prophecy.
Isa 53:8 He was taken from prison and from judgment: and who shall declare his generation? for he was cut off out of the land of the living: for the transgression of my people was he stricken.
Isa 53:9 And he made his grave with the wicked, and with the rich in his death; because he had done no violence, neither was any deceit in his mouth.
His grave was among the wicked thieves, on the cross, yet he was laid in a rich mans new tomb, where no dead had been. For his body would not see corruption.
Psa 16:10 For thou wilt not leave my soul in hell; neither wilt thou suffer thine Holy One to see corruption.
Hell in this verse is sheol, also translated the grave; among the dead.
Joseph wrapped his body in white linen. John's gospel brings in another righteous member of the council with burial spices, the pharisee Nicodemus.
John 19:39 And there came also Nicodemus, which at the first came to Jesus by night, and brought a mixture of myrrh and aloes, about an hundred pound weight.
It was Nicodemus, who believed that Jesus had come from God. Jesus had responded to him:
John 3:3 Jesus answered and said unto him, Verily, verily, I say unto thee, Except a man be born again, he cannot see the kingdom of God.
So Jesus would come from the grave a new creation, born again, the first born of a new spirit man. We follow him, being born again of God's spirit, forever alive with him in our new Spirit bodies in glory.
