Paul believed in, and had a hope of a resurrection.
Acts 23:6 King James Version
6 But when Paul perceived that the one part were Sadducees, and the other Pharisees, he cried out in the council, Men and brethren, I am a Pharisee, the son of a Pharisee: of the hope and resurrection of the dead I am called in question.
Acts 24:14-15 King James Version
14 But this I confess unto thee, that after the way which they call heresy, so worship I the God of my fathers, believing all things which are written in the law and in the prophets:

15 And have hope toward God, which they themselves also allow, that there shall be a resurrection of the dead, both of the just and unjust.
