The apostles predicted that wicked people like the teachers of false doctrine would come. They divide believers, live according to what they desire, and are devoid of God’s Spirit.

Jude 17-19

17 But you people whom I love need to remember the things that were predicted by the apostles of our Lord Jesus Christ {that the apostles of our Lord Jesus Christ said would happen}. 18 They told you, “In the final period of time in which we are now living there will be people who will laugh at the truths that God has revealed. They will do the ◄ungodly things/things that are displeasing to God► that their bodies desire.” 19 That describes the teachers of false doctrine well, because they are the ones who cause divisions among believers. They do what their own minds tell them to do. The Spirit of God does not live within them.
