[1.] Beloved, our condition needs much endurance; and endurance is produced when doctrines are deeply rooted. For as no wind is able by its assaults to tear up the oak, which sends down its root into the lower recesses of the earth, and is firmly clenched there; so too the soul which is nailed by the fear of God none will be able to overturn. Since to be nailed is more than to be rooted. Thus the Prophet prayeth, saying, “Nail my flesh by Thy fear” ( Ps. cxix. 120 , LXX.); “do Thou so fix and join me, as by a nail riveted into me.” For as men of this kind are hard to be captured, so the opposite sort are a ready prey, and are easily thrown down. As was the case of the Jews at that time; for after having heard and believed, they again turned out of the way. Christ therefore desiring to deepen their faith that it might not be merely superficial, diggeth into their souls by more striking words. For it was the part of believers to endure even reproofs, but they immediately were wroth. But how doth He this? He first telleth them, “If ye continue in My word, ye are My disciples indeed: and the truth shall make you free.” All but saying, “I am about to make a deep incision, but be not ye moved”; or rather by these expressions He allayed the pride of their imagination. “Shall make you free”: from what, tell me? From your sins. What then say those boasters?
