John 5:25-27

I assure you and most solemnly say to you, a time is coming and is [here] now, when the dead will hear the voice of the Son of God, and those who hear it will live. For just as the Father has life in Himself [and is self-existent], even so He has given to the Son to have life in Himself [and be self-existent]. And He has given Him authority to execute judgment, because He is a Son of Man [sinless humanity, qualifying Him to sit in judgment over mankind]. [Dan 7:13, 14]
