The Danger of False Teachers

³ Dear friends, I had been eagerly planning to write to you about the salvation we all share. But now I find that I must write about something else, urging you to defend the faith that God has entrusted once for all time to his holy people. 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.

⁵ So I want to remind you, though you already know these things, that Jesus^[a] first rescued the nation of Israel from Egypt, but later he destroyed those who did not remain faithful.
