Christ's enemies are but breaking their own heads in pieces, upon the Rock laid in Zion; and the stone is not removed out of its place. Faith hath cause to take courage from our very afflictions; the devil is but a whetstone to sharpen the faith and patience of the saints. I know that he but heweth and polisheth stones, all this time, for the new Jerusalem.
Samuel Rutherford (1863). “Letters of Samuel Rutherford: With a Sketch of His Life”, p.191
