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
Augustine of Hippo
AD 430
In saying, “When the Son of Man shall come, shall he find faith upon the earth?” our Lord spoke of that faith which is fully matured, which is so seldom found on earth. The church’s faith is full, for who would come here if there were no fullness of faith? And whose faith when fully matured would not move mountains? Look at the apostles themselves, who would not have left all they had, trodden under foot this world’s hope, and followed the Lord, if they had not had proportionally great faith. And yet if they had already experienced a completely matured faith, they would have not said to the Lord, “Increase our faith.” Rather we find here an emerging faith, which is not yet full faith, in that father who when he had presented to the Lord his son to be cured of an evil spirit and was asked whether he believed, answered, “Lord, I believe, help me in my unbelief.” “Lord,” says he, “I believe.” “I believe”: therefore there was faith; but “help me in my unbelief”: therefore there was not full faith.
