Hmm, for me, I think its up to the individual. What about those who have gone through a tramatic situation such as an accident, fire, or somthing that causes them to need reconstructive surgery to make them feel or look normal in society? How would one feel if it were a child or thier child who had undergone this situation such as an accident to grow up with half a face?
Whats the difference between getting a new limb or getting a new stomach cause someone lost over 150lbs and now theirs so much access of weight it makes it impossible for them to be healthy due to flab that is not removable without surgery?
There is scripture that talks about if your arm or hand causes you to sin, its better to cut it off than to sin. I know its not the same, but the principle here is. The thing is, many people go through difficulties in their appearance. Vanity is one that should not be dealt with in surgery i agree. But when it becomes more than that. A deep issue such a deep hurt or an issue that they are not a whole person becuase of something that is eating them, that it has interupted their life in some way or harming their social life to the point of isolation, then who am i or anyone to say different to say otherwise...
God says to not sin and to not let things cause us to sin.. This is something that might cause one to sin under the right situation.
How do we help each other when this happens? We can help by using the word and not being a stumbling block and giving wrong info to others when they are in difficult times. Each of us has a stumbling block in our own lives, and to each of us it might be many things... for this person it might mean this issue...
All i know is,, i am not the judge... I leave this in the capable hands of the Almighty One who is.. and for those who are going through,,, My prayers are with you,,,
