Will angels be judged by humans?
While believers are in human form they are "lower" than the angels (Hebrews 2:7-9). But after the Rapture of the church, all believers will get new glorified immortal bodies and will judge angels.
God made mankind in His image, implying that we were created to be higher than the angels when we are redeemed. He did not create angels in the image of God.
"Whoever sheds man's blood, by man his blood shall be shed; for in the image of God He made man" (Genesis 9:6).
The apostle Paul addressed the believers in Corinth with a statement saying believers will be given a higher position than angels:
Do you not know that we shall judge angels? How much more, things that pertain to this life?" (1 Corinthians 6: 3)
Also, all throughout Scripture angels have been sent buy God as servants to those who will inherent life eternal.
"Are they not all ministering spirits sent forth to minister for those who will inherit salvation?" (Hebrews 1:14)
