Every person has a different cross to bear.  In Paul’s case (from the New Testament) it was his ‘thorn in the flesh’ God would not remove despite his fervent prayers.  Sometimes prayers will resolve a situation or physical infirmity but sometimes not.  His answer is, “No.”  Every person has something different to deal with.  Sometimes, also, we create our own hell.  And sometimes it is not our fault.  It is our unique situation.  It could be fractured relationships.  Maybe, a mom or dad or sibling or friend or mate.  We can not even compare ourselves to someone else.  That really does not help.  Everyone has problems.  That is the way it is.  Every person has a different cross to bear.  It is really out of our hands.  All you can do is pray.  And change what is in your power to change.  And leave the rest up to Him.  Everything is by grace.
