Let us resist false doctrine, and contend earnestly for the faith once delivered to the saints. Let us not be ashamed of showing our colors and standing out for New Testament truth. Let us not be stopped by the cuckoo cry of “controversy.” The thief likes dogs that do not bark, and watchmen that give no alarm. The devil is a thief and a robber. If we hold our peace, and do not resist false doctrine, we please him and displease God.
