Judgment will last about 5 minutes.
Everyone will gather together in an anteroom just outside heave. Jesus the Son will stand and say “Okay everyone that accepted my salvation while alive move to right side of the room, everyone else move to left”.
God the Father will push a button and the floor of the left side of the room will drop out.
Everyone standing on the right side is saved.

Okay maybe it won’t be that easy, but that’s how I’d do it.
“...everyone that accepted my salvation ...”
Means “lived according to His word”, NOT, “thought about it once and decided it was a good idea”!
