not to be quickly shaken from your understanding or alarmed by any spirit or message or by any letter supposedly from us alleging that the day of Christ has already come.
But the day of the Lord will come like a thief in the night. On that day the heavens will pass away with a roar, the elements will be destroyed with intense heat, and the earth and its works will be burned up.
(“Behold, I am coming like a thief! Blessed is he who stays awake and keeps his garments on, so that he will not walk around naked and have people see his shame.”)
So remember what yoʋ have received and heard; obey it and repent. If yoʋ do not wake up, I will come upon yoʋ like a thief, and yoʋ will certainly not know at what hour I will come upon yoʋ.
