An excerpt from "Lifeway Voices.com" entitled, "Will The New Earth Have A Sun And A Moon?" by Randy Alcorn, states: "God Himself will be the light source for the New Jerusalem, restoring the original pattern that existed in Genesis 1 before the creation of sun and moon. Light preceded the light-holders, sun and moon, and apparently God’s very being provided that light (Genesis 1:3). So it will be again—another example of how the last chapters of the Bible reestablish something from the first chapters."
