Everyone gets put in the grave, but not everyone will walk out of it into eternal riches.
Job wasn't ready. You know when God starts a conversation by telling you to dress like a man that it is going to be good. God essentially says to Job, alright mate, put your big boy pants on, and pay attention. And then the questions begin, and they are God's questions exposing Job's limitations when compared to God's lack of those very same limitations.
Jesus prays not because He is superhuman, but because He is human. It isn't a sign of His strength that He rubs our nose in, it is evidence of His dependence on the Father that He invites us into. His early morning prayer session isn't the separated hours of spiritual practice reserved for an unhurried monk, but rather it is the life giving retreat of a very busy shepherd.
Elihu strikes me a little bit like a young man who stumbles into Calvinism for the first time. Extremely passionate, very vocal, long-winded, lacking nuance, and rapidly running out of friends to yell at.
There is a difference then between the Spirit's gifts and the Spirit's fruits. The gifts are just that...gifts, given to us as a kindness of God. The fruits though require life long growth and care. They grow out of a life of walking in the Spirit. This should still be our focus and desire, that we would grow fruit. If God has given you remarkable gift, great! Be humble, be thankful, be faithful, and walk a life that focuses on fruit and not just gift. I have met too many Christian leaders who are incredibly gifted and also jerks. The reason for this is that we celebrate gift over fruit.
The story of the covenant people of God in Genesis is a story of God's faithfulness to a people who are fighting to survive. They are exiles, sojourners, almost everywhere they go, and they face the steepest odds in every land - not to mention the odds they lengthen through their own sin - and yet they cling to a promise that God will sustain them, bless them, increase them, and get them home. That is the story arc of all of the people of God, but we forgot the whole exiles and sojourners part of it.
My relatively short experience of walking with God has shown me clearly that I learn most about God, myself, and how to walk in His love, in seasons of difficulty and distress. I like seasons of prosperity and enjoy them when they come, but prosperity can lead to a presumption of my own capability, while difficulty undeniably declares my dependence on something other than me to sustain me.
