In Job chapter 35 Elihu condemns Job. If we wonder about whether Elihu is a brash upstart, or whether he is a faithful younger man whose speech demonstrates the wisdom of God - this chapter provides us with the answer to that puzzle. And the answer is that the second statement represents Elihu's character.
Every accusation against Job, which Elihu makes, is endorsed by the Almighty in His final speeches. Elihu contests that whether you're right, or whether you sin, God is no way advantaged. However, the LORD is pleased with children whose pleasure it is to please Him. You, Job, he says must see that you are just an insignificant speck of dust. The creature cries out because of pain and suffering, but so infrequently turns to God for His love and support (Romans 8verses18-25). Surely God made us to be more than brute beasts (Ecclesiastes 3verses17-22). Job, wake up to yourself and order your speech aright before your Sovereign. In order to put things in their true perspective, for Job and his friends, in chapter 36 Elihu extols the virtues and might of our Creator. Be patient and listen, Elihu urges them. I will speak in truth and wisdom he declares. It is not the intention of the Almighty to inflict endless sufferings on the wicked (see Hebrews 12verses5-11). He is, in His wisdom, crying to the sons of men, "Repent, turn to Me and be saved". Don't go to the grave in anger and vexation. It's so easy to judge the wicked and at the same time fail to see our own failures. Learn from failure and in all things praise and thank the Almighty. Consider the magnificence of His wisdom - all creation shouts, "In wisdom You have made us".
