Jesus was given divine power by the Father, to give new life to whom He wishes. Similarly, the Father gave Jesus the power to judge all, because the Son and Father are united.
For just as the Father raises the dead and gives them life, even so the Son also gives life to whom He wishes. For not even the Father judges anyone, but He has given all judgment to the Son, so that all will honor the Son even as they honor the Father. He who does not honor the Son does not honor the Father who sent Him.
