The main idea of this passage (1 Cor. 7:17-24) is very obvious, for it is stated at the beginning (vs. 17), the end (vs. 24) and near the middle (vs. 20). Everyone who has been called to salvation should remain in the same situation of life in which he or she was called. Paul gave two examples to illustrate this command, circumcision (vv. 18-19) and slavery (vv. 21-22). The context of this passage, however, is marriage. A brother or sister (probably married before becoming a Christian) who is married to an unbeliever must remain in that marriage (vv. 12-16). A brother and sister who have divorced must remain unmarried or be reconciled (vv. 10-11). With respect to the unmarried, Paul wrote “it is good for a man to remain as he is” (vv. 25-26, cf. vs. 8). The apostle does state a reason(s) that is perhaps specific to the church at Corinth which we will consider next week (vv. 26 & 29).
However, this command, Paul ordained in all the churches! So, the general principal seems to apply to all Christians. Remain in the same situation after you become a Christian. We can see how this applies to a Christians married to an unbeliever. Certainly, they may now desire to be married to a believer. It could apply to employment in that a Christian would like to change jobs and work where there is an atmosphere more friendly to Christians. But if he or she leaves, the unbelievers who work there may not have a witness for Christ (cf. vs. 16). So, bloom where you are planted!
