1. Don’t be mislead
Jesus told them, “Don’t let anyone mislead you, for many will come in my name, claiming, ‘I am the Messiah.’ They will deceive many. And you will hear of wars and threats of wars, but don’t panic. Yes, these things must take place, but the end won’t follow immediately. Nation will go to war against nation, and kingdom against kingdom. There will be famines and earthquakes in many parts of the world. But all this is only the first of the birth pains, with more to come. “Then you will be arrested, persecuted, and killed. You will be hated all over the world because you are my followers. And many will turn away from me and betray and hate each other. And many false prophets will appear and will deceive many people. Sin will be rampant everywhere, and the love of many will grow cold. But the one who endures to the end will be saved. And the Good News about the Kingdom will be preached throughout the whole world, so that all nations will hear it; and then the end will come.
For false messiahs and false prophets will rise up and perform great signs and wonders so as to deceive, if possible, even God’s chosen ones. See, I have warned you about this ahead of time.
I can hardly believe the report about the sexual immorality going on among you—something that even pagans don’t do. I am told that a man in your church is living in sin with his stepmother. You are so proud of yourselves, but you should be mourning in sorrow and shame. And you should remove this man from your fellowship.
Your boasting about this is terrible. Don’t you realize that this sin is like a little yeast that spreads through the whole batch of dough?
When I wrote to you before, I told you not to associate with people who indulge in sexual sin. But I wasn’t talking about unbelievers who indulge in sexual sin, or are greedy, or cheat people, or worship idols. You would have to leave this world to avoid people like that. I meant that you are not to associate with anyone who claims to be a believer yet indulges in sexual sin, or is greedy, or worships idols, or is abusive, or is a drunkard, or cheats people. Don’t even eat with such people. It isn’t my responsibility to judge outsiders, but it certainly is your responsibility to judge those inside the church who are sinning.
2. Deceivers deceive themselves
Yes, and everyone who wants to live a godly life in Christ Jesus will suffer persecution. But evil people and impostors will flourish. They will deceive others and will themselves be deceived.
3. God will not tolerate unholy living
“But I have a few complaints against you. You tolerate some among you whose teaching is like that of Balaam, who showed Balak how to trip up the people of Israel. He taught them to sin by eating food offered to idols and by committing sexual sin. In a similar way, you have some Nicolaitans among you who follow the same teaching. Repent of your sin, or I will come to you suddenly and fight against them with the sword of my mouth.
“But I have this complaint against you. You are permitting that woman—that Jezebel who calls herself a prophet—to lead my servants astray. She teaches them to commit sexual sin and to eat food offered to idols. I gave her time to repent, but she does not want to turn away from her immorality.
Then you must throw this man out and hand him over to Satan so that his sinful nature will be destroyed and he himself will be saved on the day the Lord returns.
