There is one enigma..
We just assume some persons who suffer deserve better treatment by God.
However, is our evaluation of such poor and helpless factual?
Perhaps those who are suffering are in such an abysmal state, and perhaps God is propping them up with all His mercy.
Perhaps, if His help were not there, the sufferers would have been in a much worse state.
We can make a judgement about God only if we really have a measure of the mess the so-called deserving persons have created for themselves by accumulating so much of toxin in themselves.
We are trying to measure God; we either praising or berating Him, based on what is apparent to our eyes.
Our vision can be limited, our exposure to the targets of God's help or lack of it is limited. In short, our judgment cannot be error free for so many reasons.
Therefore we do not have adequate data to judge that God, if such a God is there, is lacking in Mercy for His creations, or that God is not fair to all..
Moreover, when fate closes every other door, if it opens the door of Faith, even if it is virtual or illusory, if it can just sustain our sanity, why should we not have such faith?
If one can depend on intoxicating drinks to maintain sanity in worst cases, if people use even opium and morphine to relieve excruciating pain in terminal cases, is there really anything wrong in having some faith too, if such faith can remove some pain?
We really do not know about others and their thoughts and action, we just do not know---
Even our closest associates and relatives are strangers to us in many ways.
So how do we judge their private virtues and sins and consequently judge God’s action in either granting rewards or meting out punishments?
In religion, what would work for me is good for me... We cannot compare or exchange notes in this matter.
