Jesus' kid brother told us that if we are steadfast under trial, we will receive the crown of life.  He clearly didn't think that any true God would never let us suffer at all - which is what many atheists argue today.  It's said that if there really was a God, there would be no hunger, no homelessness, no disease.  But we see that in truth when we suffer, we gain empathy for others and we are greatly empowered.  Challenges in life help us grow stronger as believers and as humans.
