21:5 all things new. Compare Acts 3:21. The “times of restitution (literally, ‘of restoration’) of all things” is finally at hand. There is a “new heaven,” a “new earth” and a “new Jerusalem,” as well as a “new name” and a “new song” (Revelation 2:17; 3:12; 5:9). Everything will be new, fresh, and perfect, just as in creation week, and they will stay that way. The entropy law (aging, decay, death, etc.) will have been “repealed,” for the curse will be gone.
21:5 true and faithful. Note Revelation 3:14; 19:11.
