Can a man be of benefit to God? Submit to God and be at peace with him

Job 22:1-30
Eliphaz replied:
It is true: Can a man be of benefit to God? Can even a wise man benefit to God? What pleasure would it give the Almighty if you were righteous? What would he gain if your ways are blameless?
To wicked on: Submit to God and be at peace with him; in this way prosperity will come to you. Accept instruction from his mouth and lay up his words in your mouth.
Eliphaz would rather invent(編湊) sins for Job than allow that his own view might be inadequate. He sticks to the same stubborn line of argument. Job is in the wrong!
Job had though to hide his sins from God. Let him make peace with God, put away his sin, and all will be well again.
Why?
Eliphaz insisted that Job is wrong and he sins against God, so Job suffered these misery.
Some words of Eliphaz are truth that man's altitude or contribution can not benefit to God.
To a wicked man if he turn to the Lord, submit to God will be at peace with him.
How?
We do the good things and to be righteous are our responsibility, to honor his Holy name, it is our feedback to God's love.
