The plain truth is that false doctrine has been the chosen engine which Satan has employed in every age to stop the progress of the Gospel of Christ.
J. C. Ryle
"The human instruments which God uses in great triumphs of faith are no pacifists, but great fighters like Paul himself."
(Uttered in his last sermon preached at Princeton Theological Seminary.)
J. Gresham Machen
"False religion may cause persons to be loud and earnest in prayer."
"That religion which is not spiritual and saving may cause men . . . to delight to delight in hearing the word of God preached."
"If the actings of grace do much decay in the Christian, and he falls into a lifeless frame, he loses his assurance: but this kind of confidence of hypocrites will not be shaken by sin: they (at least some of them) will maintain their boldness in hope, in the most corrupt frames and wicked ways: which is a sure evidence of their delusion."
"Assurance is not so much to be gained by self-examination as by action."
"A true love to God must begin with a delight in His holiness, and not with a delight in any other attribute."
