O Jerusalem, is not in Hebrew or St. Jerome, but in the Septuagint. Some few things may refer to the terrestrial Jerusalem, though the prophet speaks chiefly of the celestial and of the Church. — Lord, very great. Christ came to save us. (Calmet) — God prevents by his grace, but man must co-operate to be justified. (Worthington)
This whole chapter is all to the same purport, all in the same strain; it is a part of God's covenant with his church, which is spoken of in the last verse of the foregoing chapter, and the blessings here promised are the fruits of the word and Spirit there promised. The long continuance of the church, even unto the utmost ages of time, was there promised, and here the large extent of the church, even unto the utmost regions of the earth; and both these tend to the honour of the Redeemer. It is here promised, I. That the church shall be enlightened and shone upon, ver 1, 2. II. That it shall be enlarged and great additions made to it, to join in the service of God, ver 3-8. III. That the new converts shall be greatly serviceable to the church and to the interests of it, ver 9-13. IV. That the church shall be in great honour and reputation among men, ver 14-16. V. That it shall enjoy a profound peace and tranquility, ver 17, 18. VI. That, the members of it being all righteous, the glory and joy of it shall be everlasting, ver 19-22. Now this has some reference to the peaceable and prosperous condition which the Jews were sometimes in after their return out of captivity into their own land; but it certainly looks further, and was to have its full accomplishment in the kingdom of the Messiah, the enlargement of that kingdom by the bringing in of the Gentiles into it, and the spiritual blessings in heavenly things by Christ Jesus with which it should be enriched, and all these earnests of eternal joy and glory.
Verses 1-8 As far as we have the knowledge of God in us, and the favour of God towards us, our light is come. And if God's glory is seen upon us to our honour, we ought, not only with our lips, but in our lives, to return its praise. We meet with nothing in the history of the Jews which can be deemed a fulfilment of the prophecy in this chapter; we must conclude it relates principally to future events. It predicts the purity and enlargement of the church. The conversion of souls is here described. They fly to Christ, to the church, to the word and ordinances, as doves to their own home; thither they fly for refuge and shelter, thither they fly for rest. What a pleasant sight to see poor souls hastening to Christ!
The time of thy prosperity and felicity: whereas speaking of Babylon, he commanded her to go down, Isa. 47:1 .
I. It shall be very lightsome: Thy light has come. When the Jews returned out of captivity they had light and gladness, and joy and honour; they then were made to know the Lord and to rejoice in his great goodness; and upon both accounts their light came. When the Redeemer came to Zion he brought light with him, he himself came to be a light. Now observe, 1. What this light is, and whence it springs: The Lord shall arise upon thee (v. 2), the glory of the Lord (v. 1) shall be seen upon thee. God is the father and fountain of lights, and it is in his light that we shall see light. As far as we have the knowledge of God in us, and the favour of God towards us, our light has come. When God appears to us, and we have the comfort of his favour, then the glory of the Lord rises upon us as the morning light; when he appears for us, and we have the credit of his favour, when he shows us some token for good and proclaims his favour to us, then his glory is seen upon us, as it was upon Israel in the pillar of cloud and fire. When Christ arose as the sun of righteousness, and in him the day-spring from on high visited us, then the glory of the Lord was seen upon us, the glory as of the first-begotten of the Father. 2. What a foil there shall be to this light: Darkness shall cover the earth; but, though it be gross darkness, darkness that might be felt, like that of Egypt, that shall overspread the people, yet the church, like Goshen, shall have light at the same time. When the case of the nations that have not the gospel shall be very melancholy, those dark corners of the earth being full of the habitations of cruelty to poor souls, the state of the church shall be very pleasant. 3. What is the duty which the rising of this light calls for: "Arise, shine; not only receive this light, and" (as the margin reads it) "be enlightened by it, but reflect this light; arise and shine with rays borrowed from it." The children of light ought to shine as lights in the world. If God's glory be seen upon us to our honour, we ought not only with our lips, but in our lives, to return the praise of it to his honour, Matt 5 16; Phil 2 15.
People. Babylon shall suffer, while thou art relieved. (Calmet) — The Gentiles continue in darkness till they embrace the faith, ver. 3. (Haydock) — Only those who are in the Church receive the light of truth. (Worthington)
Rising. The three wise men were the first. [Matthew ii.]
1. What shall invite such multitudes to the church: "They shall come to thy light and to the brightness of thy rising, v. 3. They shall be allured to join themselves to thee," (1.) "By the light that shines upon thee," the light of the glorious gospel, which the churches hold forth, in consequence of which they are called golden candlesticks. This light which discovers so much of God and his good will to man, by which life and immortality are brought to light, this shall invite all the serious well-affected part of mankind to come and join themselves to the church, that they may have the benefit of this light to inform them concerning truth and duty. (2.) "By the light with which thou shinest." The purity and love of the primitive Christians, their heavenly-mindedness, contempt of the world, and patient sufferings, were the brightness of the church's rising, which drew many into it. The beauty of holiness was the powerful attractive by which Christ had a willing people brought to him in the day of his power, Ps 110 3.
