This horse has been beaten for a long time and now it is waking up from its death bed, defying all the taunts aimed at it. Finally someone has the answers for why we suffer.
God allowing suffering has four main causes. Suffering can come from your own sin, the sin of others, God testing you, or so that God might be glorified through it; unfortunately, if one of these is not the case then we are not certified to seek an explanation. Endurance will bear fruit. These unfortunate situations will ultimately bring glory to God.
Apart from sin being an imaginary ailment created by pastors to have a reason to offer their cure, why would an omni anything test you? How warped is this kind of thinking? And how can one say if any of the answers above doesn’t deal with your case, then you can’t seek an explanation. There is no room for redress. God can fuck us all he cares and we can’t ask why? Thanks goodness, no gods have been found anywhere. In the end we suffer so that god can receive glory. Now you know the answer.
We are further given scripture readings that absolve god from telling men why they suffer. The OP writes
“Does a clay pot dare argue with its maker, a pot that is like all the others? Does the clay ask the potter what he is doing? Does the pot complain that its maker has no skill? Do we dare say to our parents, ‘Why did you make me like this?’ The Lord, the holy God of Israel, the one who shapes the future, says: ‘You have no right to question me about my children or to tell me what I ought to do! I am the one who made the earth and created human beings to live there.’”-Isaiah 49:9-12
We also get a passage from Job, which doesn’t answer why we suffer only that we shouldn’t complain when god makes us suffer. The author writes
Consider the joy of those corrected by God! Do not despise the chastening of the Almighty when you sin. For though he wounds, he also bandages. He strikes, but his hands also heal.”-Job 5:17-18
