Elihu had several good things to say to Job. I especially liked this from chapter 35, verse 10. Elihu said: He is the One who gives us songs to sing in the night.
In our darkest hour, when all seems lost, when we turn to Him and are reminded of who it is that we rely on, and His power and grace and glory, we can sing songs of praise and worship because we know that God is on the throne. I know this because I have been there. I have lain in my bed in the middle of the night, and have felt His presence and poured my heart out to Him, and felt His peace settle over me. And it is in those times when He gives us songs to sing.
During Elihu’s discourse, Elihu pointed out some errors Job made in his statements, but he did not attack Job’s character unlike Job’s other friends. Job in his suffering did say some untrue things about God, and Elihu addressed those things. He reminded Job that God is God, and Job is not. That’s a good reminder, and one that I am all too glad to embrace. I don’t want the job!
