Yes. It IS a Pleasure to the Almighty When We Are Righteous

Is it any pleasure to the Almighty that you are righteous?
Or is it gain to Him that you make your ways blameless?
Job 22:3

Eliphaz is in error because he has no concept of God's grace. This puts him in a category with the devil. It is true that we cannot profit God at all, but one of the wonders of the gospel is that when we are righteous, it is by His grace. It is by His own righteousness. And He is genuinely delighted with our righteousness, because He Himself is our righteousness. Read the Song of Songs, and other passages like Zeph 3:17. It is one of the glories of the gospel that the Lord does genuinely delight in His people. While the friends say many true things about right and wrong, and blessing and curse, their view of God is abbreviated, their view of blessing is abbreviated, and their view of grace is abbreviated.
