“Wherein it is shewn, that strangers were more ready to receive the faith, but Israel was slow to believe; and so it follows, And he said unto him, Arise, go thy way, thy faith has made thee whole.”

“And He said unto him, Arise, go thy way: thy faith. Faith, Digitized by Google 430 by which you have believed that I am able to save you, nay that I will do so, if you obey Me, and go to the priests. For this faith has worked with your healing, even though I be the primary author. Hence very likely the prompting of God elicited from this leper some act of contrition by which he was justified ; and that he then left the schism of the Samaritans, and joined the true religion of the Jews. In the end he became a disciple of Jesus, and received His baptism, and became a Christian and preached the power and miracle of Christ and converted many to Him. Ver. so. — And when He was demanded of the Pharisees , The Kingdom of Israel, which had now indeed fallen, but which was to be raised up again by the Messiah. The kingdom of God cometh not with observation, “ Cometh,” th at is, will come. It is a Hebraism, in which the present is put for the future. Observe that Christ said, “Repent, for the kingdom of God is at hand.” This Pharisee, therefore, either from a desire of knowledge, or to mock Jesus, said, “Thou Jesus preachest Thy kingdom in heaven, but when will it come? When shall we see Thee reigning in it? When shall we see Israel, who is now subjugated by the Romans, breathe again through Thy means and recover her liberty and live happily under Thee as her king?” “ They asked Him when He would reign,” says Euthymius, “ as to deride Him, who appeared as one of low estate.” But Christ answered mildly and briefly at first as in this verse, but afterwards at more length (verse 22 to the end of the chapter). He spoke of the glory of His kingdom in the heavens, to which that of grace should first be subordinated on earth, for we proceed to glory through grace. He said therefore, The kingdom of God, The kingdom of God and the Messiah cometh not with previous preparation, nor with the outward pomp of soldiers, horses, and chariots, as you can see, from itself You know a king to be at hand when you see his attendants preceding him. With such as these you thought that the kingdom of the Messiah would come, and you look for it as now nigh at hand. Ver. 2 1. — Neither shall they say. They shall not say, In Jerusalem is Digitized by Google THE KINGDOM OF GOD. 43* the royal throne of Christ, He reigns there in magnificence like another Solomon ; because Christ does not reign on a bodily throne, but in a spiritual soul, which by His grace He rules and directs into all good, and so guides it to the kingdom of heaven. For the kingdom of God is not meat and drink, but righteousness, and peace, and joy in the Holy Ghost^ Rom. xiv. 17. I would understand all these sayings of the same thing : that is, of the first Advent of Christ, in which He reigns in the souls of the faithful as a king through His grace ; for thus do His sayings, as a whole, best agree together and cohere. Some, however, understand the kingdom of glory, because He will adorn even the bodies of the just with His own brightness, and other gifts, as all may see. Secondly, This kingdom of God is within us : that is, it is in our own power if we embrace the faith and grace of Christ, and work with Him, for, as Titus says, “ It is of our own will and power to receive the kingdom of God.” Thirdly, The kingdom of God is within us, because Christ, as our God and king, lives among us preaching and endowing this kingdom. Thus speaks Theophylact : “ The kingdom of God on the whole is to live after the manner of the angels, when nothing of this world occupies our souls. We need no long time and no distant journey, for faith is near us, and after faith the divine life.” The same also said the Apostle, “The word is nigh thee, in thy mouth and in thy heart, that is, the word of faith,” Rom. x. 8. For to believe, and to walk worthily of our belief and of our calling, is within us. The Pharisees therefore derided the Lord, but He turned them into ridicule, showing that they were ignorant of that which was within them and which is very easy to any one who wishes for it. " For now when I am in the midst of you, you are able to possess the kingdom of God if you believe in Me and will live according to My commandments.””

“And when he was demanded of the Pharisees,.... Or "asked" by them; who expected the Messiah, and that when he was come he would set up a temporal kingdom, and deliver them from the Roman yoke; when they should enjoy great liberty, peace, and prosperity; so that they might put the following question to Christ in a serious manner, agreeably to these expectations: or it may be occasioned by the frequent mention that had been made of the kingdom of God by John, and Christ, and his disciples in their ministry, and so be put in a way of derision; or, as most of their questions were, with a view to ensnare or puzzle: when the kingdom of God should come; either the kingdom that God had promised, or the kingdom of the Messiah, who is truly God, that had been so often spoken of by John the Baptist, Christ, and his apostles. The Ethiopic version reads, "the kingdom of heaven", which is the same with the kingdom of God; for these phrases are promiscuously used. This question they need not have asked, had they carefully attended to the writings of the Old Testament they had in their hands; and had they diligently observed the signs of the times, in which they lived; and had they seriously regarded the ministry and miracles of Christ among them; from these things, they might have concluded, not only that the time was at hand, when the kingdom of God should be set up, but that it was already come: they might have observed, that not only the harbinger of the Messiah was come, who was John the Baptist; but that the Messiah himself was among them, by the many wonderful things which he wrought among them, and by the many Scripture prophecies which were fulfilled in him; they might have seen that the sceptre was manifestly departing from Judah; that all power and authority were falling into the hands of the Romans; and that only a mere shadow and appearance of it were among them; they might have known, by calculation, that the time fixed in Daniel's prophecy, for the coming of the Messiah, was now up, and therefore he must be come; and they had very good reason to believe that Jesus was he. He answered them and said, the kingdom of God cometh not with observation; or so as to be observed by the eye, or to be distinguished when it comes as the kingdoms of this world, by outward pomp and splendour, by temporal riches, external honours, and worldly power and grandeur; though it so far came with observation, that had they had eyes to see, they might have observed that it was come, by what they saw done by Christ, particularly the power that he showed in the dispossessing devils out of the bodies of men; see Mat 12:28. The Syriac version reads, "with observations"; and some understand the words of the observances of the ceremonies of the law, of days, months, and years, and the difference of meats, and the like, which the kingdom of God is not in, and which were to cease upon its coming; but the former sense is best.”

“Thy faith hath made thee whole. Were not the others also made whole? They were cleansed indeed from their leprosy, but it no where appears that they were justified in their souls like this Samaritan, of whom it said, thy faith hath made thee whole; whereas it was said of the others, that they were made clean, viz. of their leprosy in their body, though not justified in their soul: this the Samaritan alone seems to have obtained.
