"The book of Revelation says that we no longer need the sun or the moon, for Christ is the light of the world"

This quote from Tim LaHaye is describing a passage from the book of Revelation in the Bible. In this passage, it is stated that the sun and the moon will no longer be required, as Christ is the light of the world. This is a metaphor for the spiritual light that Christ gives the world. It is a tip that Christ is the source of all light and hope, and that we must aim to Him for guidance and strength. This quote is a tip that we ought to not count on earthly things for our salvation, however instead turn to Christ for our spiritual requirements. It is a suggestion that Christ is the ultimate source of light and hope, which we ought to seek to Him for assistance and strength.
