I take an arginine product that raises nitric oxide. This is effective in keeping the circulatory system clean. I want to also take glucosamine for my back but I read that Glucosamine lowers nitric oxide levels. It appears that it may not make sense to take both but that I need to choose which is more important to me, my back or my heart.

I understand that you believe that faith is required. So salvation is not exactly free. So what if someone pretends to have faith and asks the prayer for salvation. What if he had faith at one time but changed his mind. What about baptism? is it required? Also, what is faith? is it a meer wish or does it involve faithfulness and a struggle to do Gods will? What if one guy says I wish to go to heaven and another says I do not believe? Does this mean one will go to heaven and the other will burn forever?
