This is probably a wacky question, but I received an email yesterday that claims the anti Christ will be in his early 40’s. I don’t recall seeing any absolute physical description of this being. Is there any specific description of the anti Christ in scripture except the use of the pronoun “he”?
There is no Biblical basis for the information you received. The closest thing we have to a physical description of the anti-Christ is in Zechariah 11:17:
“Woe to the worthless shepherd, who deserts the flock! May the sword strike his arm and his right eye! May his arm be completely withered, his right eye totally blinded!”
