become united with him in the likeness of his death ... be united with his resurrection

Paul compares our union with Christ to death. Those who are joined with Christ in death will share in his resurrection. You can translate this in an active form. Alternate translation: "died with him ... come back to life with him" (See: rc://en/ta/man/jit/figs-metaphor and rc://en/ta/man/jit/figs-activepassive)
