I believe in God an there is nothing wrong with asking for healing(however you word it) because it cant hurt.
Jesus, Buddha etc all them healed people in thier lifetimes. It could happen. But like you all say, dont just sit back and do nothing constructive, try and help yourself.
You can't believe both Jesus and Buddha are God. Believing in one contradicts the belief of the other...Just thought I'd point that out
And yeah, I totally agree with you on this. Your internal health is what effects your skin. However, I was merely saying it's possible for God to heal it, but that doesn't mean he will just because he can, so it's best to be as healthy as possible and try to fight acne as best as you can internally and externally.
Your skin is a reflection of your internal health, that's just common sense.
