"'If God places no trust in his servants, if he charges his angels with error, how much worse those who live in houses of clay, whose foundations are in the dust, who are crushed more readily than a moth!'" NIV translation
Eliphaz reminds Job that even the most righteous of men are below the angels and God removed Satan and his followers from heaven for their sin.
"'Between dawn and dusk they are broken to pieces; unnoticed, they perish forever. Are not the cords of their tent pulled up, so that they die without wisdom?'" NIV translation
Eliphaz reminds Job that life is short which is true but he also seems to say that the things a man does are unnoticed and insignificant. That may be partially true but it also misses out on the point that God has things for all people to do and that He is involved in our daily lives.
This is the main difference between religion and saving faith. A saving faith is a daily walk with the Lord while religion is like trying to pay someone to be your friend.
In the words of Eliphaz, we clearly see that he did not have a saving faith but instead was trapped in a religious way of thinking. We are also reminded of the fact that Job was not trying to elevate himself to a position above God but had simply been crying out for answers. Religion basically says that we cannot know the answers to the things of God while saving faith says we can ask God for answers and trust that His answer is always right and best.
