God’s design was perfectly to restore all the ruins of the fall, so far as concerns the elect part of the world, by his Son; and therefore we read of the restitution of all things. Acts iii. 21. “Whom the heaven must receive, until the times of the restitution of all things; and of the times of refreshing from the presence of the Lord Jesus.” Acts iii. 19. “Repent ye therefore and be converted, that your sins may be blotted out, when the times of refreshing shall come from the presence of the Lord.”
Man’s soul was ruined by the fall; the image of God was defaced; man’s nature was corrupted, and he became dead in sin. The design of God was, to restore the soul of man to life and the divine image in conversion, to carry on the change in sanctification, and to perfect it in glory. Man’s body was ruined; by the fall it became subject to death. The design of God was, to restore it from this ruin, and not only to deliver it from death in the resurrection, but to deliver it from mortality itself, in making it like unto Christ’s glorious body. The world was ruined, as to man, as effectually as if it had been reduced to chaos again; all heaven and earth were overthrown. But the design of God was, to restore all, and as it were to create a new heaven and a new earth: Isa. lxv. 17. “Behold, I create new heavens, and a new earth; and the former shall not be remembered, nor come into mind.” 2 Pet. iii. 13. “Nevertheless we, according to his promise, look for new heavens, and a new earth, wherein dwelleth righteousness.”
The work by which this was to be done, was begun immediately after the fall, and so is carried on till all is finished, when the whole world, heaven and earth, shall be restored. There shall be, as it were, new heavens, and a new earth, in a spiritual sense, at the end of the world. Thus it is represented, Rev. xxi. 1. “And I saw a new heaven, and a new earth; for the first heaven and the first earth were passed away.”
