Revelation 21:25

The gates of it shall not be shut at all - The Christian Church shall ever stand open to receive sinners of all sorts, degrees, and nations.

There shall be no night there - No more idolatry, no intellectual darkness; the Scriptures shall be everywhere read, the pure word everywhere preached, and the Spirit of God shall shine and work in every heart.

And the gates of it shall not be shut at all by day - It shall be constantly open, allowing free ingress and egress to all who reside there. The language is derived from Isaiah 60:11. See the notes on that place. Applied to the future state of the blessed, it would seem to mean, that while this will be their permanent abode, yet that the dwellers there will not be prisoners. The universe will be open to them. They will be permitted to go forth and visit every world, and survey the works of God in all parts of his dominions.

For there shall be no night there - It shall be all day; all unclouded splendor. When, therefore, it is said that the gates should not be "shut by day," it means that they would never be shut. When it is said that there would be no night there, it is, undoubtedly, to be taken as meaning that there would be no literal darkness, and nothing of which night is the emblem: no calamity, no sorrow, no bereavement, no darkened windows on account of the loss of friends and kindred.
