You are proposing your god as the " basic of morals "
The divine guide , dictates the rules that you call "morality "
What rules ?
---> the rules of Allah - and the sharia ?
---> the rules of YAHWE - and the Thora ?
---> The hindu rules ? etc ...
---> The unfaillible decrees of the pope ?
---> The tenets of the moral majority ?
---> The habits of the ruling class in your society
---> The dictates/teachings of your church
---> The writings and life of the "divine Oarsmen" Mao-tse-toeng ?
---> The conventions in your society considered by the elderly as " good " ?
---> Julius Caesar ? Napoleon ?
---> The "deep truths " sayings of dementing popular lunatics considered very " wise men "
and why do you think that one of these is " more moral" then the others ?
You even can state that the non-believers are immoral and therefore can be exploited
and exterminated in a "moral justified " way,____ why, it was ordered by God ?
Simple
the Morals are the morals imposed by the ruler/ ruling classes and societies that survive ...
That's why there are punishments attached to morals and "laws " , because without them they
have no real power to control the behaviour of people under those laws ...
Without executive power, any imposed reglementation is mere bluff ....
What you call morality
are the rules to maintain a certain society running ....
Obedience and surrender to these rules is based on
psychological mechanisms
Apprenticeship and initiation rituals
education
conditioning
and yes brute force ....
But most of all the human need to live in any social setting that is beneficial to the
reproduction power of the concerned population ....
Particular "Morals' are the norms in any society
there never was "another "base
And the divine is nothing else but the " ghostly "representation of the "society "
itself ...
God is nothing else but the "Swarm Intelligence" in a large men-nest
( compare it to caravan- ants colonnes )
And yes , haven't you noticed :
the "morals" change if the societies survival is under attack /environmental stress
and
That's a fact ... not a much desired goal ...
If the morals decline in present societies the reason is "OVERPOPULATION" and the increased
competition for supplies and materials that keep these societies running ...
