The apostle exhorts to steadfastness in
the faith 1-4. The danger of being infected by false professors, and
the dreadful punishment which shall be inflicted on them and their
followers 5-7. An awful description of these seducers and their
deplorable end 8-16.
Believers cautioned against being surprised at such deceivers
arising among them 17-23. The epistle ends with an encouraging
doxology, or words of praise 24,25.
