What is Perseverance?

"The perseverance of the saints is a steady pressing forward in the course on which they entered at conversion—an enduring unto the end in the exercise of faith and in the practice of holiness. The perseverance of the saints consists in a continuing to deny self, to mortify the lusts of the flesh, to resist the Devil, to fight the good fight of faith; and though they suffer many falls by the way, and receive numerous wounds from their foes, yet, if "faint," they "hold on their way." —A. W. Pink (1886–1952)
