This author talked about the antichrists and deceivers. They do not acknowledge Jesus Christ in the flesh. Do not lose what you have, your full eternal reward. God is not with those who do remain with the teachings of Jesus Christ. However, if you abide in Christ, then God is with you. Do not greet people who do not bring the teaching of Christ, because to greet them is to participate in their wicked evil ways. Do you greet people who are wicked?
