The evidence of genuine piety

(John Angell James, "The Christian Professor")

The evidence of genuine piety is to be found in . . .
  real humility,
  self-distrust,
  hungering and thirsting after righteousness,
  sorrow for sin, and
  a continual effort to regulate your thoughts,
    feelings, and conduct by the Word of God.

Genuine piety will not thrive and increase without
effort--but is of so tender and delicate a nature as
to require great, constant, and persevering concern,
watchfulness, and care.
