Commentary on Isaiah Volume 2 John Calvin (continued)
COMMENTARY ON ISAIAH
But when we shall be perfectly renewed, heaven and earth shall also be fully renewed, and shall regain their former state. And hence it ought to be inferred, as we have frequently remarked, that the Prophet has in his eye the whole reign of Christ, down to its final close, which is also called
"the day of renovation and restoration." (Acts 3:21.) 18. But rejoice ye and be glad for ever. He exhorts believers to rejoice, in such a manner as they ought, on account of such a benefit bestowed by God. And this was added for the sake of amplification; because men do not adequately consider God's other benefits, and especially that which is the highest and most excellent of all; for either they disregard them altogether, or value them less than they ought to do. On this account believers must be aroused and urged by such exhortations as these, that they may not chew themselves to be unthankful or unmindful, or think that it ought to be lightly passed by, that, having been redeemed by the hand of Christ, they carry in their hearts the pledge of eternal and heavenly life. That is the reason why Isaiah chews that believers do not give due praise for redemption in any other way than by continuing their joy through the whole course of their life, and employing themselves in celebrating the praises of God.
For, lo, I create Jerusalem a rejoicing, and her people a joy. At first sight this might be thought harsh; but an excellent meaning is obtained, that the ground of joy in the deliverance of the Church shall be so great as to remove every cloud of sadness. And, indeed, since even afflictions aid our salvation, (Romans 8:28,) we have good reason for rejoicing in them.
19. And I will be glad in Jerusalem. He expresses more than in the preceding verse; for by these words he means that he not only will give to men ground for rejoicing, but even will be a partaker with them in that joy. So great is his love toward us, that he delights in our prosperity not less than if he enjoyed it along with us. And hence we obtain no small confirmation of our faith, when we learn that God is moved, and so powerfully moved, by such an affection toward us. If we are in painful and distressed circumstances, he says that he is affected by grief and sorrow; and, on the other hand, if our condition is pleasant and comfortable, he says that he takes great pleasure in our prosperity. Hence also we have formerly seen that "the Spirit of the Lord is sad and vexed," (Isaiah 63:10,) when that order which he demands and approves is overturned and confounded; and in another passage he takes upon himself the character of a husband who is satisfied with the love of his wife. (Isaiah 62:5.)
20. There shall be no more thence an infant of days. Some think that this points out the difference between the Law and the Gospel; because "the Law, as a schoolmaster," (Galatians 3:24,) kept scholars in the first elements, but the Gospel leads us on to mature age. Others suppose it to mean that there will no longer be any distinction of age; because, where life is eternal, no line is drawn between the child and the old man. But I interpret the words of the Prophet in this manner, "Whether they are children or old men, they shall
