Measure

"...even though now for a little while, if necessary, you have been distressed by various trials, so that the proof of your faith, being more precious than gold which is perishable, even though tested by fire, may be found to result in praise and glory and honor at the revelation of Jesus Christ"

I noticed that ringing particular true just looking at Job's life compared to that of David.  Job's friends were not entirely wrong in saying that God doesn't inflict people unjustly.  I think their main error was thinking that they could pigeonhole sin.  They were seemingly thinking that Job did something wrong.  In reality, Job didn't do anything wrong until his friends brought him down that path of thought.  And God straightened him out on the spot and in person.  And examining Job's life overall, with the exception of that shrouded detour, lasting , what, a couple years? Maybe? his life was rather prosperous. David on the other hand was inflicted with pain almost his entire life.  And the moment life became easy for him, he committed adultery , and then murdered so he could cover it up.  God's discipline is not unjust.  

"Who shall separate us from the love of Christ? Shall tribulation, or distress, or persecution, or famine, or nakedness, or danger, or sword?"

This life if anything becomes more difficult when you accept Christ's invitation into His kingdom.  

"For I consider that the sufferings of this present time are not worth comparing with the glory that is to be revealed to us."
