Job 19:26 (NIV)
...yet in my flesh I will see God.
One doesn't need God when things are going well. We don't discover ourselves in prosperity, we lose our minds. Only suffering, trials and tribulations test a man/woman's true beliefs. Job lost everything he had, his children, wealth, friends and even his health. Yet, he resolutely clung to the hope that someday God would vindicate him. That kind of unshakable faith in Christ is what sets a saint apart from a casual church goer.
