2 Thessalonians 2:8-12

8And then gthe lawless one will be revealed, whom the Lord Jesus hwill kill with ithe breath of his mouth and bring to nothing by jthe appearance of his coming. 9The coming of the lawless one is by the activity of Satan kwith all power and false signs and wonders, 10and with all wicked deception for lthose who are perishing, because they refused to love the truth and so be saved. 11Therefore mGod sends them a strong delusion, so that they may believe nwhat is false, 12in order that all may be condemned owho did not believe the truth but phad pleasure in unrighteousness.
