1 Corinthians 7:10 And unto the married I command, yet not I, but the Lord, Let not the wife depart from her husband:
11 But and if she depart, let her remain unmarried, or be reconciled to her husband: and let not the husband put away his wife.
Paul writing here to the married people is just saying if you are married you should stay married. The couple can work for the Lord while they are married. The word says one can put a thousand demons to flight then two can put ten thousand to flight, so it is beneficial for the two to work together. When this scripture says depart it is the same as divorce and if a spouse leaves then they should remain unmarried or be reconciled to the other spouse. Divorce today is rampant and the Bible says the only cause for divorce is because one spouse is unfaithful. The union of husband and wife is to be a permanent arrangement. As long as they bond as one in Lord they should never have any reason for separation of any kind.
