A task far, far beyond the poor resources of fallen human nature!

(Arthur Pink "Saving Faith" 1948)

O my reader, be not deceived on this vital matter:
  to mortify the lusts of the flesh,
  to be crucified unto the world,
  to overcome the Devil,
  to die daily unto sin,
  to live unto righteousness,
  to be . . .
    meek and lowly in heart,
    trustful and obedient,
    pious and patient,
    faithful and uncompromising,
    loving and gentle;
in a word, to be a Christian, to be Christlike — is a task far, far beyond the poor resources of fallen human nature!

The demands of Christ are . . .
  too humbling to our natural pride,
  too searching for the callous conscience,
  too exacting for our fleshly desires.
A miracle of grace has to be wrought within us before this awful depravity of our nature, this dreadful state of affairs, is changed!
