John Chrysostom

There is … a human righteousness that depends on external laws, but it is inferior, possessing nothing perfect and complete, arising from human deliberation. It is your righteousness, on the contrary, that I seek, that has come down from you and leads up to heaven.… The present life, you see, is a way on which guidance from on high is required. I mean, if we want to enter a city, we need someone to show us the way; much more if we are to travel to heaven do we have need of grace from above to point out and determine the way and guide us on it. There are many paths to lead us astray, after all. Hence let us hold God's right hand.
