Whenever I read Job 38, I find myself smiling but I know Job was not smiling as he listened to the Lord. I always imagine his posture as God lectured him about His greatness, omnipotence, His glorious majesty, wondrous deeds, the magnificence of His handiwork, etc. I bet Job laid face down in awe, ashamed, a bit confused, humbled and sober.
Job is a wealthy and "upright man" with a large family. God decides to boast about Job to Satan. Satan counters by saying Job is good and righteous because God has blessed and prospered him. God allows Satan to take away all Job has, afflict his body but cannot take his life. One day out of the blue disaster strikes and in one full swoop Job losses everything: children, wealth, property. His wife is spared and Job is left with excruciatingly painful sores on his body.
Naturally Job has many questions. His friends try to help him make sense of the why, though they do not help much with their long winding debates and theological expositions on why God has punished Job and on who God is. Job oscillates between self righteousness and frustration, justifying himself at times, justifying God's actions at other times and lashing out at God. Confused he also has many questions and prays that God will answer him.
God does answer him, not in the way Job expected; for God's answer came in the form of questioning. In five chapters starting with chapter 38, God "answers" Job. In the end Job and his friends realized the folly of trying to understand God's ways; the futility of trying to understand God with the limited knowledge available to man. After Job hears all God has to say he soberly concludes, "...Surely I spoke of things I did not understand, things too wonderful for me to know." Job 42:3
I know you have questions about your own life, the lives of others and about the world. You want to know why God has not done this or has allowed that. Why He will not answer your questions or reveal His plans clearly and plainly to you. I know you get frustrated at times and sometimes you just want to give up on Him and this Christian walk. God is a good God, nothing happens to us or around us that He does not see or does not know of. Ours is to trust Him and not try to figure Him or His ways out. That will only lead to more frustrations. We must trust Him for what we do understand knowing that all will work together for our good.
