During the Christmas season I reflected on Jesus coming as the light of the world (John 8:12; 9:5; 12:46). I thought of how many songs and decorations are associated with light. In all the darkness of the world, we need his light.
Today I read a thought connecting theology and science by Andy Walsh in a blog on Jesus Creed called “It Is All Relative”. He points out that there are many principles in science which are constant. One is the speed of light in a vacuum, about 300 million meters per second. This is true regardless of the relative speed of the one seeing the light. The only objects which can actually move at the speed of light are things without mass, such as protons.
Much of our society today is preaching that all morals and truths are relative. They do not understand how Christians believe in absolutes. That is because they do no know Jesus. He is our absolute, our constant in goodness, truth and morals. Though he was tempted in the same ways we are, he remained sinless (Hebrews 4:15). This makes him the only one who, morally speaking moves at the speed of light (without the weight of sin). Our goal is to “walk in the light as he is in the light” 1 John 1:7.
