In these closing words of his letter, Paul gives his final words to the church, hoping that the next time they will hear from him will be in person. In the first four verses, Paul encouraged the wayward brothers and sisters to repent of their sin and promised to deal sternly with those who would not. Secondly, in verses 5-10, he pleads with the brothers and sisters to give serious attention to the nature of their relationship with Jesus and the genuineness of their salvation so that they might be sure of their salvation.
