For book worms out there who are interested in theology, I highly recommend Dove Booksellers. I have added a link to their site on the sidebar. The reason I recommend them is that about %50 of the books they sell are unavailable anywhere else. For books that they sell that other companies sell (especially or WTS bookstore), I would not recommend them. But for specialized books, it is impossible to beat Dove. They actually sell German theological books! I haven’t been able to find German theological books anywhere on the net (and be able to purchase them using the English language!). Highly recommended.


I love light. I can’t stand to work in darkness, or even a partly dark room. For a job that requires as much reading as a pastor’s position, light is absolutely essential. But light is essential for life itself. Plants do not grow without it, and people can do nothing without it. Sinclair Ferguson tells the story of one night spent in Canada far away from any city. It was a cloudy night. As a result he could not see his hand even if held right in front of his eyes. It was truly pitch-black.

When Jesus says that we are the light of the world, He is saying that we are a reflected light. Jesus says, “I am the light of the world” in John 8:12 and 9:5. If Jesus is the Sun, then we are the moon, reflecting the light of Jesus. The moon reflects the light of the sun. Just as one cannot look directly at Jesus’ glory and live (in this already/not yet time period), so also one cannot look directly at the sun and keep one’s vision. However, one can look at the moon. Its light waxes and wanes, but it retains its light, except for the new moon (okay, the analogy doesn’t fit entirely). One can know what the sun does by looking at the moon. So also, the world is to see what Jesus’ light looks like by looking at us. We should be shining brightly, as at the full moon.

Saltiness 2

An interesting thing about salt is that it does no good unless it is in constant contact with the food. Jesus says that we are the salt of the earth. On another occasion He mentions the fact that we should be in the world, but not of the world. He says that same thing in Matthew 5, when He says that we are the salt of the earth.

Salt as sodium chloride can never lose its saltiness. However, in the first century, salt was usually found with other elements or compounds. Since the sodium chloride was the most water soluble of any of the things found with it, it could often leech out if it was left out in the rain, or if it got wet for some other reason. What was left was good for nothing except to repair the roads. This explains what could otherwise be a rather inexplicable passage. Salt is a relatively stable compound, and so to say that salt could become non-salt was a contradiction in Jesus’ day (we could change it today, I suppose, if anyone really wanted to). That is, one could not change the chemical make-up of salt, though one could leech it out of the mix in which it was found.

But salt was primarily used to preserve meat from decay. If used in this way, it had to be in constant contact with the meat. Salt even an inch away from the meat did no good. And yet, Jesus tells us that the salt cannot become unsalty. Here we have it: in the world and not of the world.

A second use of salt is to flavor. Some scholars do not think that that is part of the analogy here, since so much of food had to have a lot of salt in it just in order to preserve it. However, other foods that did not salt for preservation nevertheless might taste better with salt. So the analogy still holds. we are to add zest to life, just as we are to preserve the world from utter corruption.

In a book entitled _Chameleon Christianity_, Dick Keyes tells us that there are two dangers to avoid in the Christian life. One is the “herd mentality,” where everyone is protective such that no exposure to the world is possible. These people are not preserving the world from decay, since they have no contact with the world. Some of the hermetic tradition falls into this trap. The other (and equal) danger is assimilation into the culture. The church has too much contact with the world, and so looks just lie the world. In Jesus’ terms, either the salt isn’t even contacting the meat (herd mentality), or it has lost its saltiness (chameleon Christianity). If we are to be true salt, then we must avoid both dangers.
