HONESTLY, that thought has never really crossed my mind: probably becuz I feel that the only one I have really let down is MYSELF! I have been a believer and follower of JESUS CHRIST all my life, so I hope I am becoming a better person for that, but I am far from perfect and GOD knows that very well. He is a LOVING and FORGIVING GOD.
Firstly, I diidn't become overweight on purpose; GOD knows that! He also knows our intentions and thoughts. I am just doing my best to live as healthy as I can. I also think that life is a school and we are the pupils.
GOD knows that we live in a society that shoves unhealthy food at us all the time; and some of us were not taught how to eat healthy either. Some of us eat from emotions becuz we have suffered or been too stressed. GOD is a compassionate GOD; and I think that he not only LOVES us and CARES ABOUT US, but he wants to help us too.
I ask GOD in prayer daily to give me strength and wisdom to make more excellent choices. I look around for the advice of those here who are doing well; I even believe that GOD has directed us to find this great place for support. And, I read the bible every day, and I have never found anything in there that makes me feel badly about myself; it only seems to be other people who do that ...
I believe that GOD wants me to start TRUSTING HIM for better health, and not to rely on others; and to live in a healthy, balanced way. That means to be more concerned with good health and moderation, not vanity. Sometimes we are just way too hard on ourselves, and then we project that on to GOD too.
I agree with everything SCRAVER has said (thank you dear). I also think that we need to forgive ourselves more. Forgive myself for listening to the wrong people. Forgive myself for not seeing what was going wrong sooner. Forgive myself for being flawed and weak. BUT, what's most important to me now is that I know that GOD LOVES ME AND CARES FOR ME; so, now I can start taking better care of myself with HIS help.
