Psalms 12:5

13. "And the Lord God set a mark upon Cain, lest any one finding him should slay him." It is a most notable fact, that all the nations subjugated by Rome adopted the heathenish ceremonies of the Roman worship; while the Jewish nation, whether under Pagan or Christian monarchs, has never lost the sign of their law, by which they are distinguished from all other nations and peoples. No emperor or monarch who finds under his government the people with this mark kills them, that is, makes them cease to be Jews, and as Jews to be separate in their observances, and unlike the rest of the world. Only when a Jew comes over to Christ, he is no longer Cain, nor goes out from the presence of God, nor dwells in the land of Nod, which is said to mean commotion. …

5. “Lest at any time mine enemy say, I have prevailed against him” ( ver. 4 ). The devil’s mockery is to be feared. “They that trouble me will exult, if I be moved;” the devil and his angels; who exulted not over that righteous man, Job, when they troubled him; because he was not moved, that is, did not draw back from the stedfastness of his faith.

11. “Deliver me not over, O Lord, by my own longing to the sinner” ( ver. 8 ). Behold to what end Thy overshadowing shall avail for me, that I suffer not heat from myself. And what could that “sinner” do to me, rage as he would? For wicked men raged against the martyrs, dragged them away, bound them with chains, shut them up in prisons, slew them with the sword, exposed them to wild beasts, consumed them with fire: all this they did; yet did not God deliver them over to the sinners, because they were not delivered over by their own longing. This then pray with all thy might, that God “delivered thee not over by thine own longing to the sinner.” For thou by thine own longing givest place to the devil. …

But our belief is that they undertake this struggle not without effort on their part. For in their conflict they themselves have some sort of anxiety and depression, and especially when they are matched with stronger rivals, i.e., saints and perfect men. Otherwise no contest or struggle, but only a simple deception of men, and one free from anxiety on their part would be assigned to them. And how then would the Apostle’s words stand, where he says: “We wrestle not against flesh and blood, but against principalities, against powers, against world-rulers of this darkness, against spiritual wickedness in heavenly places;” and this too: “So fight I, not as one that beateth the air;” and again: “I have fought a good fight”? For where it is spoken of as a fight, and conflict, and battle, there must be effort and exertion and anxiety on both sides, and equally there must either be in store for …

Whence human reason cannot easily decide how the Lord gives to those that ask, is found by those that seek, and opens to those that knock, and on the other hand is found by those that sought Him not, appears openly among those who asked not for Him, and all the day long stretches forth His hands to an unbelieving and gainsaying people, calls those who resist and stand afar off, draws men against their will to salvation, takes away from those who want to sin the faculty of carrying out their desire, in His goodness stands in the way of those who are rushing into wickedness. …
