When I was at BJU it was a common practice and frowned upon for a married man to speak with a single/married woman. I mean calling/emailing/ etc.. The Bible is quote clear on sexual immorality and this thread is not about that, but what if the married man wishes to evangelize the other woman, or what if he wishes to connect with her and get to know her so he can network better and get a job reference and or a job? Is this unbiblical? Loading people down with too many rules will not take the place of the Holy Spirit. But the reality is that an evangelist will seek to win any sex over to the Lord, and a unemployed person will network all he can to land a good job. What do you say?
