One of the most difficult questions for an atheist to answer is, “who says so?” When it comes to deciding morality atheism has no leg to stand on. While most organized religions have a sacred book to guide them the atheist has no point of reference for right and wrong.
Lying, stealing, killing, cheating, covetousness and additional social “evils” are forbidden within the pages of scripture. But what about an atheist?
The atheist can not appeal to a higher authority as a source for morality. Steal from an atheist. He will think it is wrong. But ask him why stealing is wrong and you will have a problem. His best answer will be because I said so. The only appeal can be from within because there is no higher authority. Atheistic reasoning has no concrete morality to appeal to. It has no sacred book or deity.
The founding fathers understood that morality is a result of creation. In the Declaration of Independence we find their admission that “We are endowed by our creator with certain unalienable rights.”
Consider the social consequences of individual people deciding morality. It would be impossible to function as a society. This is why to progress as people Faith in God’s word is essential. Who says so? Certainly not me. “Without faith it is impossible to please Him.” –God (Hebrews 11:6)
