Why have You set me as Your target [God]?...For He [God] bruises me with a tempest, and multiplies my wounds without cause.
Job is in the middle of the suffering. He has no idea of the scenario being played out in heaven between God and Satan (described in Job 1-2). Job's mind sought for a reason why he was suffering. Not finding an answer in his own reasoning, he assumed that there wasn't a reason and stopped trusting God!
No wonder God's response to Job later was to say, "Who is this that darkens counsel by words without knowledge" (Job 38:2). Job didn't know about the confrontation between God and Satan. He didn't realize that he was not even the main character in the situation. He couldn't see what God's purpose and plan was. He didn't know that God would restore and bless him at the end of the test. And he lost sight of the greatness of God.
As humans, we are capable of enduring almost any suffering, so long as we know there is a reason for it!
Are you facing suffering or pain today? God is reminding you to trust Him. Even when you can't imagine a reason for your suffering, you can trust God that there is a reason (Romans 8:28). He will bring good out of this for you.
Take some time to express your trust to God right now.
