Is having facial hair considered to be a sin. There are some preachers that say it is a sin or rebellion. But, is it truly rebellion if a man wants to have facial hair. It is only rebellion if the man starts off being convicted then stops living out his conviction . What it really boils down to is obedience . There were many men in the bible that had facial such Moses and Jesus . There are even verses in the Old Testament on grooming of facial hair. I believe where a lot of people get off on this issue is they try to relate it to salvation. When we begin to do this we actually are adding to the salvation. So, we need to be careful in this area and not to go too far out of bounds..
