Maybe you feel that the origins of holidays have little to do with how they are celebrated today. Do origins really matter? Yes! To illustrate: Suppose you saw a piece of candy lying in the gutter. Would you pick up that candy and eat it? Of course not! That candy is unclean. Like that candy, holidays may seem sweet, but they have been picked up from unclean places. To take a stand for true worship, we need to have a viewpoint like that of the prophet Isaiah, who told true worshipers: "Touch nothing unclean."—Isaiah 52:11.
How about that? Substitute "a piece of candy" for "Cola Cube" and you've managed it three times ???
Desparate I know, but it may keep you smiling on the inside.
