The main themes of this letter are about correct teaching, ethics, and eschatology, the end times. There is a mention of seven virtues so that Christians should lead a life above reproach. However, there were false teachers that they had to be careful about. They should not fall into debauchery, errors, and lose hope. They had to have correct authoritative Christian revelation that included the Old Testament and the words of the apostles. Jesus Christ has delayed this Second Coming to give them time to repent. These are the themes that dominate this letter. Do you have correct Christian teachings, lead a good life, and expect Christ to return?
