You are either Christian are you are not.
You either accept Christ or you do not.
You either have faith or do not.
If you are fretting into a cold sweat in your sleep out of fear you may be conforming to something Christianity is not for you; you either accept God's will or rebel against it.
When I was baptized, I accepted Jesus Christ. My bases are covered. Either that or I was lied to by the Christians. Either way, no fretting into a cold sweat here. The ones that should be fretting are the ones coming here and lying in the name of God. That is a major sin that will keep you out of heaven.
