In Bible we find that God leaves us an example of a group of people who go through the life-is-unfair experience. And their response?
Instead of becoming cynical and selfish and ready to quit, the Apostle Paul heaped praise on them because
Their faith actually grew in the face of unfair treatment.
Their love for others actually increased, even when the world was out to get them.
And instead of abandoning the faith, their steadfastness became an example for believers all over the known world to follow.
