We are agog
A "man" arrives on the world scene ? Are you getting this idea from the bible or from a teaching of man ?
"Performs miracles" are you talking about Revelation Chapter 13 ? 11Then I saw a second beast, coming out of the earth. It had two horns like a lamb, but it spoke like a dragon."
14Because of the signs (https://biblehub.com/greek/4592.htm) it was given power to perform on behalf of the first beast, it deceived the inhabitants of the earth."
The question is , would you know the signs or would you be deceived by them ?
