Peter – If there is no God who created us then the only alternative is that we just unintentionally happened to come into existence.

If we have unintentionally happened into existence then there is no ultimate purpose for our existence.

If there is no purpose for our existence then things are not meant to be one way or another.

If things are not meant to be one way or another then nobody can do anything that is “right” or “wrong”.

Neither can there be any goal toward which we are meant to “progress”.

In your bio at the end of your article you describe yourself as an “ethicist”. In a godless universe no one can do right or wrong so there can be no meaningful ethics.

Yes, of course we can have laws but there is no necessary connection between law and morality. Just because a law declares an act to be “wrong”, that does not make it immoral.

No, if there is no God, then the teaching of Jesus and Christianity is just so much hot air as is the teaching of any “ethicist”, including yourself.

If you are a rational atheist, “ethics” is simple: just do whatever you think you can get away with. End of story.

The contents of this book which has an amusing title provide all the evidence/arguments re the existence of The Living Divine Reality.

The author provides a comprehensive critique of both adolescent scientism and the essentially childish, even infantile persuasions promoted by institutional exoteric Christian-ISM.

Christian-ISM being a set of half-baked ideas about what we are as human beings and the nature of Reality altogether.

This book titled Religion & Reality too: http://global.adidam.org/books/religion-reality

This reference provides an Illuminated Understanding of what we are as human beings, and a comprehensive set of guidelines re how to live a fully authentic and truly moral way of life.

"If we have unintentionally happened into existence then there is no ultimate purpose for our existence."
Why should there be?

Precisely ateday.

If there is no God our lives are ultimately completely meaningless. We just happen to come into being for no reason, live a number of years for no reason, and then die and go into oblivion.

JP. That probably sums it all up pretty well.
