⁴ I say this because some ungodly people have wormed their way into your churches, saying that God’s marvelous grace allows us to live immoral lives. The condemnation of such people was recorded long ago, for they have denied our only Master and Lord, Jesus Christ.

⁴ Even that question came up only because of some so-called believers there—false ones, really^[a]—who were secretly brought in. They sneaked in to spy on us and take away the freedom we have in Christ Jesus. They wanted to enslave us and force us to follow their Jewish regulations.

The Danger of False Teachers

2 But there were also false prophets in Israel, just as there will be false teachers among you. They will cleverly teach destructive heresies and even deny the Master who bought them. In this way, they will bring sudden destruction on themselves. ² Many will follow their evil teaching and shameful immorality. And because of these teachers, the way of truth will be slandered. ³ In their greed they will make up clever lies to get hold of your money. But God condemned them long ago, and their destruction will not be delayed.

¹⁰ He is especially hard on those who follow their own twisted sexual desire, and who despise authority.

These people are proud and arrogant, daring even to scoff at supernatural beings^[a] without so much as trembling.

¹⁵ Everything is pure to those whose hearts are pure. But nothing is pure to those who are corrupt and unbelieving, because their minds and consciences are corrupted. ¹⁶ Such people claim they know God, but they deny him by the way they live. They are detestable and disobedient, worthless for doing anything good.

²² And who is a liar? Anyone who says that Jesus is not the Christ.^[a] Anyone who denies the Father and the Son is an antichrist.^[b]

¹⁸ They brag about themselves with empty, foolish boasting. With an appeal to twisted sexual desires, they lure back into sin those who have barely escaped from a lifestyle of deception. ¹⁹ They promise freedom, but they themselves are slaves of sin and corruption. For you are a slave to whatever controls you. ²⁰ And when people escape from the wickedness of the world by knowing our Lord and Savior Jesus Christ and then get tangled up and enslaved by sin again, they are worse off than before. ²¹ It would be better if they had never known the way to righteousness than to know it and then reject the command they were given to live a holy life. ²² They prove the truth of this proverb: “A dog returns to its vomit.”^[a] And another says, “A washed pig returns to the mud.”

¹⁶ For you are free, yet you are God’s slaves, so don’t use your freedom as an excuse to do evil.

⁵ And God did not spare the ancient world—except for Noah and the seven others in his family. Noah warned the world of God’s righteous judgment. So God protected Noah when he destroyed the world of ungodly people with a vast flood. ⁶ Later, God condemned the cities of Sodom and Gomorrah and turned them into heaps of ashes. He made them an example of what will happen to ungodly people.

⁸ And,

They stumble because they do not obey God’s word, and so they meet the fate that was planned for them.
