And therefore I measure not the truth and favor of God by having or by lacking of bodily necessities, but by the promise which He has made to me. As He Himself is immutable, so is His word and promise constant, which I believe, and to which I will adhere, and so cleave, whatever can come to the body outwardly." In this answer of Christ we may perceive what weapons are to be used against our adversary the devil, and how we may confute his arguments, which craftily, and of malice, he makes against God's elect. Christ might have repulsed Satan with a word, or by commanding him to silence, as He to whom all power was given in heaven and earth; but it pleased His mercy to teach us how to use the sword of the Holy Ghost, which is the word of God, in battle against our spiritual enemy. The Scripture which Christ brings is written in the eighth chapter of Deuteronomy. It was spoken by Moses a little before His death, to establish the people in God's merciful providence. For in the same chapter, and in certain others that go before, He reckons the great travail and divers dangers with the extreme necessities that they had sustained in the desert the space of forty years, and yet, notwithstanding how constant God had been in keeping and performing His promise, for throughout all perils He had conducted them to the sight and borders of the promised land. And so this Scripture more directly answers to the temptation of Satan; for thus does Satan reason, as before is said, "Thou art in poverty and hast no provision to sustain thy life. Therefore God takes no regard nor care of Thee, as He doth over His chosen children." Christ Jesus answered: "Thy argument is false and vain; for poverty or necessity precludes not the providence or care of God; which is easy to be proved by the people of God, Israel, who, in the desert, oftentimes lacked things necessary to the sustenance of life, and for lack of the same they grudged and murmured; yet the Lord never cast away the providence and care of them, but according to the word that He had once pronounced, to wit, that they were His peculiar people; and according to the promise made to Abraham, and to them before their departure from Egypt, He still remained their conductor and guide, till He placed them in peaceable possession of the land of Canaan, their great infirmities and manifold transgressions notwithstanding."
