From The Valley of Vision:
I know that thou art the author and finisher of faith,
that the whole work of redemption is thine alone,
that every good work or thought found in me is the effect of thy power and grace,
that thy sole motive in working in me to
will and to do is for thy good pleasure.
O God, it is amazing that men can talk so much about man's creaturely power and goodness,
when, if thou didst not hold us back every moment,
we should be devils incarnate.
This, by bitter experience, thou hast taught me concerning myself.
