There're many religion in the world, some religion have the principle of "if you disobey my God then you'll go to hell or receive punishment".
Here is a conversation, believer from religion A-F preach to a non-believer.
Religion A: You must obey my God, otherwise you'll go to hell for forever.
Religion B: You must obey my God, otherwise you'll receive serious punishment from my God.
Religion C: You must obey my God, otherwise you'll be burning for forever.
Religion D: You must obey my God, otherwise you'll be agony for eternity.
Religion E: You must obey my God, otherwise you'll be regret forever.
Religion F: You must obey my God, otherwise you'll be curse by my God for eternity.
What worries me is what if one of those turn out to be true?
Anyways, there is also the following:
Religion A: If you obey my God, you'll go to heaven forever.
Religion B: If you obey my God, you'll receive serious rewards from my God.
Religion C: If you obey my God, you'll be happy forever.
Religion D: If you obey my God, you'll be in peace for eternity.
Religion E: If you obey my God, you'll be appreciate it forever.
Religion F: If you obey my God, you'll be loved by my God for eternity.
Half glass full
But what I believe in is that following a specific religion for believing it is the truth and good for oneself and for others is more important than doing so out of fear or love for what would come out of it, not that the latter is not a good reason for some people of course. If that level is reached, I believe it is the ultimate possible case scenario.
