and earth, &c., and rested the seventh _period_, (_y=x_;) therefore the Lord blessed the seventh _period_, and hallowed it” The reason, in its character as a reason of proportion, survives here in all its integrity. Man, when in his unfallen estate, bore the image of God, but it must have been a miniature image at best;—the proportion of man’s week to that of his Maker may, for aught that appears, be mathematically just in its proportions, and yet be a miniature image too,—the mere scale of a map, on which inches represent geographical degrees. All those week days and Sabbath days of man which have come and gone since man first entered upon this scene of being, with all which shall yet come and go, until the resurrection of the dead terminates the work of Redemption, may be included, and probably _are_ included, in the one Sabbath day of God.
