Elihu declares that Job's words have been empty since he lacks the knowledge he seeks: why he is suffering and why be righteous if you are going to suffer anyway? No one can obtain knowledge that is hidden by God, therefore, rather than get bogged down in trying to make ourselves worthy of God's grace, through faith we will receive God's grace and comfort. It is God's action for us, and He promises to be with us in the creation. Our righteousness is not a means to an end, but an outgrowth of the righteousness Christ gives to us. We should redirect our words away from empty speculations to praying to God in faith.
