There are representations of Jesus everywhere, e.g. in children’s books with stories of the Bible. There is nothing wrong with them. But religious pictures (icons) of Jesus should be avoided. We do not need material things to worship God. (2 Cor. 5:6) The Bible clearly states: “Flee from idolatry.” (1 Cor. 10:14) The word “idolatry” is Greek. It is a compound word of two parts: “idol+latria.” In Greek, idol means the reflection of something, for example, of yourself in a mirror. Latria means worship. But the exact meaning of the word latria in ancient Greek is holy/sacred service. So idolatry actually means holy service to a reflection of whatever. So if you feel that a picture or a statue is given religious attention in some way, you can easily fall into idolatry. The idea is that you can get attached to it so much as to feel uncomfortable to throw it into the dustbin if, for example, it is damaged or you have found a better replacement. You should also consider how others feel about it. Would they feel offended if you destroyed something that they regard as holy? To avoid such an awkward situation exclude pictures specifically made for worship in some religion. Another problem is the argument that “I use it just like I would have used a picture of my father on my desk.” That’s a shallow argument. We don’t know what Jesus looked like and certainly he did not walk around with a disc (a halo) on his head. If your father had died when you were a baby, would you have the picture of any man on your desk and call him “father”? Would he really remind you of your father? Wouldn’t you rather try to find out as much about him as you can? Which comes to: Read your Bible Daily.
