15 To the pure all things are pure, but to those who are defiled and unbelieving nothing is pure; but even their mind and conscience are defiled. 16 They profess to know God, but in works they deny Him, being [a]abominable, disobedient, and disqualified for every good work.
17 Now I urge you, brethren, note those who cause divisions and offenses, contrary to the doctrine which you learned, and avoid them. 18 For those who are such do not serve our Lord [a]Jesus Christ, but their own belly, and by smooth words and flattering speech deceive the hearts of the simple.
8 Look to yourselves, that [a]we do not lose those things we worked for, but that we may receive a full reward.

12 Beware, brethren, lest there be in any of you an evil heart of unbelief in departing from the living God; 13 but [a]exhort one another daily, while it is called “Today,” lest any of you be hardened through the deceitfulness of sin.
3 For all the nations have drunk of the wine of the wrath of her fornication, the kings of the earth have committed fornication with her, and the merchants of the earth have become rich through the [a]abundance of her luxury.”
17 Even so,every good tree bears good fruit, but a bad tree bears bad fruit.18 A good tree cannot bear bad fruit, nor can a bad tree bear good fruit.19 Every tree that does not bear good fruit is cut down and thrown into the fire.20 Therefore by their fruits you will know them.

8 And then the lawless one will be revealed, whom the Lord will consume with the breath of His mouth and destroy with the brightness of His coming. 9 The coming of the lawless one is according to the working of Satan, with all power, signs, and lying wonders, 10 and with all unrighteous deception among those who perish, because they did not receive the love of the truth, that they might be saved. 11 And for this reason God will send them strong delusion, that they should believe the lie,
