Matthew 4:6

What then doth this accursed one? Overcome, and unable to persuade Him to do his bidding, and that when pressed by such violent hunger, he proceeds to another thing, saying, "If Thou be Son of God, cast Thyself down; for it is written, He shall give His angels charge concerning Thee, and in their hands they shall bear Thee up." What can the reason be, that at each temptation He adds this, "If Thou be Son of God?" Much the same as he did in that former case, he doth also at this time. That is, as he then slandered God, saying, "In the day ye eat, your eyes shall be opened;" thereby intending to signify, that they were beguiled and overreached, and had received no benefit; even so in this case also he insinuates this same thing, saying, "in vain God hath called Thee Son, and hath beguiled Thee by His gift; for, if this be not so, afford us some clear proof that Thou art of that power." Then, because Christ had reasoned with him from Scripture, he also brings in a testimony of the prophet. But mark thou his folly, even by the very testimony which he produced. For while the testimonies cited by the Lord were both of them spoken with exceeding fitness: his, on the other hand, were chance and random sayings, neither did he bring forward on his part that which applied to the matter in hand. For that it is written, "He shall give His angels charge concerning Thee," this surely is not advice to dash and toss one's self down headlong; and moreover, this was not so much as spoken concerning the Lord. However, this for the time He did not expose, although there was both insult in his manner of speech, and great inconsistency. For of God's Son no man requires these things: but to cast one's self down is the part of the devil, and of demons. Whereas God's part is to raise up even them that are down. […]

He tempts through vainglory when he says: "If you are the Son of God, cast yourself down." By the same means by which the ancient enemy tempted our first parent through vainglory when he said "You shall be as gods," so he now tempts the second Adam: but by the same means by which he boasted of having conquered the first man, he is conquered by the second man.

It should be noted, that though our Saviour suffered Himself to be placed by the Devil on a pinnacle of the temple, yet refused to come down also at his command, giving us an example, that whosoever bids us ascend the strait way of truth we should obey. But if he would again cast us down from the height of truth and virtue to the depth of error we should not hearken to him. Otherwise, it was a suggestion to Him, as man, that He should seek by requiring some miracle to know the greatness of God's power.

(ap. Anselm.) We must explain thus; Scripture says of any good man, that He has given it in charge to His Angels, that is to His ministering spirits, to bear him in their hands, i. e. by their aid to guard him that he dash not his foot against a stone, i. e. keep his heart that it stumble not at the old law written in tables of stone. Or by the stone may be understood every occasion of sin and error.

And said to him: "If you are the Son of God, throw yourself down." The devil always strikes with two arrows: for with the one he entices to vain glory, with the other to suicide. And this is if you are the Son of God. …

Then the devil taketh Him up into the Holy City, and setteth Him on a pinnacle of the temple, and saith unto Him, If Thou be the Son of God, cast Thyself down: for it is written, He shall give His angels charge concerning thee, …

He was also right in applying it to Christ, for to him all the promises of the protection of the saints primarily and eminently belong, and to them, in and through him. That promise, that not a bone of theirs shall be broken ( Ps. xxxiv. 20 ), was fulfilled in Christ, John xix.

And saith unto him, if thou be the Son of God,....

Cast thyself down - Our Lord had repelled the first temptation by an act of confidence in the power and goodness of God; and now Satan solicits him to make trial of it. Through the unparalleled subtlety of Satan, the very means we make use of to repel one temptation may he used by him as the groundwork of another. This method he often uses, in order to confound us in our confidence. He shall give his angels charge, etc. - This is a mutilated quotation of Psa 91:

He shall give his angels charge concerning thee: and in their hands--rather, "on their hands." they shall bear thee up, lest at any time thou dash thy foot against a stone--The quotation is, precisely as it stands in the Hebrew and the Septuagint, save that after the first clause the words, "to keep thee in all thy ways," are here omitted.

The first event in our Lord’s ministry which St. Matthew records after his baptism is his temptation. This is a deep and mysterious subject. There is much in the history of it which we cannot explain; but there lie on the face of the history plain practical lessons, to which we should do well to take heed. Let us learn in the first place, what a real and mighty enemy we have in the devil. He is not afraid to assault even the Lord Jesus himself.

The first event in our Lord’s ministry which St. Matthew records after his baptism is his temptation. This is a deep and mysterious subject. There is much in the history of it which we cannot explain; but there lie on the face of the history plain practical lessons, to which we should do well to take heed. Let us learn in the first place, what a real and mighty enemy we have in the devil. He is not afraid to assault even the Lord Jesus himself. Three times over he attacks God’s own Son: our Saviour was “tempted of the devil.” It was the devil who brought sin into the world at the beginning. This is he who vexed Job, deceived David, and gave Peter a heavy fall: this is he whom the Bible calls a “murderer,” a “liar,” and a “roaring lion” ( John 8:44 ; 1 Peter 5:8 ); this is he whose enmity to our souls never slumbers and never sleeps; this is he who for nearly 6,000 years has been working at one work, to ruin men and women and to draw them to hell; this is he whose cunning and subtlety pass man’s understanding, and who often “appears an angel of light.” ( 1 Corinthians 11:14 ) Let us watch and pray daily against his devices. There is no enemy worse than an enemy who is never seen and never dies, who is near us wherever we live, and goes with us wherever we go. Not least, let us beware of that habit of foolish talking and jesting about the devil which so unhappily common. Let us remember that if we would be saved we must not only crucify the flesh and overcome the world, but also “resist the devil.” Let us learn in the next place that we must not count temptation a strange thing. “The disciple is not greater than his master, nor the servant than his Lord.” If Satan came to Christ, he will also come to Christians. It would be well for believers if they would remember this. They are too apt to forget it.

THE clearest and most important exposition of the Revelation of God in the inspired Book is the Revelation of God in the renewed man. Every Christian will discover, in proportion to his advances in Divine knowledge, that the very things which are written in these hallowed pages are written in his own experience. We never fully understand Divine Truth until we have experienced it. The diamond of Divine promise never glistens so brightly as when it is placed in the setting of personal trial and experience.

THE clearest and most important exposition of the Revelation of God in the inspired Book is the Revelation of God in the renewed man.

We never fully understand Divine Truth until we have experienced it. The diamond of Divine promise never glistens so brightly as when it is placed in the setting of personal trial and experience. And the gold of sacred Truth is not valued until it has been tried "so as by fire." Holy Scripture is full of narratives of temptations. Expect, therefore, Christian, that your life will be as abundantly garnished with them as is a rose with thorns. Provision is made in the Word of God for the assaults of Satan from all quarters and in all fashions—believe, therefore, most confidently that the wise provisions of forethought are not made in vain—but will be needed in your own proper person. You will have to do battle with those spiritual foes which have beset and buffeted other saints in days gone by, and you will be wise to array yourself in those pieces of heavenly armor which proved to be so great a safeguard to them in their seasons of warfare. This remark, that the Word of God is written out again in the life of the Christian, is emphatically true in that part of it which concerns the life of Jesus. Every Christian is the image of Christ in proportion as he is a Christian—in proportion as the Spirit sanctifies us—spirit, soul, and body. As the Spirit makes us like the Master we are conformed to Him. And this not only in the holiness and spirituality which sanctification produces, but also in our experience of conflict, sorrow, agony, and triumph.

And saith unto him, If thou be the Son of God, cast thyself down - The temptation here was, that he should at once avail himself of the protection of a promise of safety made to him, and thus demonstrate that he was the Messiah. If he was the true Messiah he had a certain assurance of protection, a promise that no harm could befall him; and thus, by so surprising a miracle, and such a clear proof of the divine interposition, he could at once establish his claim to the Messiahship. How much more easy would this be than to engage in a slow work of years to establish that claim; to encounter fatigue, and want, and poverty, and persecution, before that claim would be admitted! And where could be a more suitable place for thus at once demonstrating that he was the Son of God, than on this pinnacle of the temple, in the very midst of Jerusalem, and perhaps in the presence of thousands who would see the wonderful performance? The temptation, therefore, in this case was, that by thus establishing his claim he would avoid all the obloquy, persecution, and suffering which he must otherwise endure if he attempted to prove that he was the Son of God by a life of toil and privation. It is written - That is, there is a passage of Scripture which promises special protection in such a case, and on which you may rely. The argument was not, perhaps, that this applied exclusively to the Messiah, but that, if applicable in any case, it would be in this; if any one could plead this promise, assuredly he could who claimed to be the Son of God. He shall give his angels charge concerning thee ... - That is, they shall protect thee. And in their hands they shall bear thee up - They shall sustain thee, or hold thee up, so that thou shalt not be endangered by the fall. Lest at any time thou dash thy foot against a stone - This would be especially appropriate in such a case. […]

Jesus didn't argue. He quoted Scripture—every time. That's our model. We don't overcome with cleverness or willpower. We overcome by knowing and declaring God's Word.
