(1Co 7:36) “But if any man think that he behaveth himself uncomely toward his virgin, if she pass the flower of her age, and need so require, let him do what he will, he sinneth not: let them marry.” So, the teaching is not that there is sin in marrying. It is that there are periods of time (ours may be coming), during times of persecution, that one would be better off single. This frees one to make the hard decisions of self sacrifice for the glory of our Savior!
