And immediately the father of the child cried out, and said with tears, Lord, I believe; help my unbelief.
All Commentaries on Mark 9:24 Go To Mark 9
John Cassian
AD 435
Seeing that his faith was being driven by the waves of unbelief on the rocks which would cause a fearful shipwreck, he asks of the Lord an aid to his faith, saying “Lord, help me in my unbelief.” So thoroughly did the apostles and those who live in the gospel realize that everything which is good is brought to completion by the aid of the Lord, and not imagine that they could preserve their faith unharmed by their own strength or free will, that they prayed that it might be helped and granted to them by the Lord.
