My sister in law recently got saved (about 4 months ago). She also, within the last month and a half, got a new boyfriend. They have started a pretty serious relationship and he is moving back to his home state of Mississippi. She is now planning on moving with him. My husband and I (along with a few others) have talked to her about how this is not according to God's plan but she doesn't seem to have a problem with it. She also was looking for something in the Bible that would tell her this is wrong. Could you please give me any insight as to what is the Biblical answer to this situation? Thanks.
