The Bible speaks of four different days in the sense of long periods of time. Each one of these days marks a separate and distinct period of time. These are not meaningless expressions. There are four references of these days in Scripture. They are called:  (1) Man’s Day, (2) The Day of Christ, (3) The Day of the Lord, and (4) The Day of God. The good workmen will identify the four days and, then, “rightly divide” them.
