9 The coming [of the lawless one, the antichrist] is through the activity and working of Satan and will be attended by great power and with all sorts of [pretended] miracles and signs and delusive marvels–[all of them] lying wonders–
10 And by unlimited seduction to evil and with all wicked deception for those who are perishing (going to perdition) because they did not welcome the Truth but refused to love it that they might be saved.
11 Therefore God sends upon them a misleading influence, a working of error and a strong delusion to make them believe what is false,
12 In order that all may be judged and condemned who did not believe in [who refused to adhere to, trust in, and rely on] the Truth, but [instead] took pleasure in unrighteousness.
13 But we, brethren beloved by the Lord, ought and are obligated [as those who are in debt] to give thanks always to God for you, because God chose you from the beginning as His firstfruits (first converts) for salvation through the sanctifying work of the [Holy] Spirit and [your] belief in (adherence to, trust in, and reliance on) the Truth.
14 [It was] to this end that He called you through our Gospel, so that you may obtain and share in the glory of our Lord Jesus Christ (the Messiah).
15 So then, brethren, stand firm and hold fast to the traditions and instructions which you were taught by us, whether by our word of mouth or by letter.
