22:2 Eliphaz third speech contains the question: Can an able-bodied man be of use to God himself, that anyone having insight should be of use toward him?
Many people today are plagued with negative feelings about themselves.
Satan and his demons want us to feel that what we do is not good enough for God!
They take delight in crushing a person.
If they can influence an individual to feel that nothing he does is good enough for God, he is more vulnerable. In time, such a person could drift away from the living God.
So it is important that we avoid such thinking and instead meditate on examples from the past where Jehovah have shown himself to be the God of Love (1 John 4:8)
