Even if we assume that god exists and even if we assume that it wants us to follow a specific morality, can we be reasonably certain that god wants us to follow that specific morality?
If so, then by what means or method do we know that god wants us to follow a specific morality?
Wonderful Question.
I will try to explain this with an example .
If a room is well lit , fully illuminated, would one have any difficulty walking around, wouldn't the dangers be clear , crystal clear.
Now , If the light gets faded , the vision become blurry , will not the obstruction become equally dim?.
Now , imagine an extreme third situation , where there is no light in the room , pitch dark , what do you think will happen in such a situation ? will we not stumble to each and every obstruction?
The same is the case with us , If the light within us is well lit we can see every thing clearly , if blurred we may need some assistance and if too low we may not see any thing , not able to identify what is right or wrong i.e what is morally correct .
Now , since it is great that you believe in a God and one God(or at least assume) , it becomes very easy to explain.
We believe that God is one and we all are his children ( spiritual) and that God is good.
So , what should be the original qualities of these godly children ?, shouldn't they be good , same as that of The Father.
Speaking about a good God , what qualities could you imagine for Him? , lets make a small list.
It would be all things nice like , Love , Power , Happiness , Peace , Knowledge, Bliss ..
Once we recognize these to be the qualities of the Father soul ,and that we are His beloved children , His image, we realize that we also have this fuel deep within us , all we need is just to dig it out and lit our lights by igniting this fuel.
At Brahmakumaris we do this digging and illuminating by meditation and positive affirmations , by constantly reminding that these are my original values , I am the child of Supreme Father who is the Ocean of Love , Peace , Power...
Once this light is lit , it illuminates your world around , now instead of asking yourself if something is right or wrong you may start asking , Does this suit the Child of God?
