Verses 3-16 Jude’s letter is a message to Christians about false
teachers, who were teaching wrong things. Those teachers said that they
themselves were Christians. But they were very dangerous, because they were
stopping some people from obeying God. God is very angry with false teachers
like that, and he will *punish them.
Verses 17–23 So Jude tells the Christians that they must be very
careful. They must continue to believe the right things that belong to God’s
true message. They must continue to love God and other people. They must try to
help their friends who have believed the wrong things.
We do not know which Christians Jude was writing to. Nor do we
know when he wrote his letter. But Jude’s message is very important for all
Christians at any time.
