Truth doesn’t change. It becomes more fully revealed. Absolute truth, that is. Not relative truth, that thing that is so prevalent in today’s American society.
Let’s use science as an example. At extremes of speed and gravity, Isaac Newton’s Laws of Motion and Gravity begin to fail. Along comes Albert Einstein with the Theory of Relativity, which perfectly explains the deviations scientists observed. Moreover, Einstein’s theories and calculations fail when taken to the center of a black hole. So scientists have to work on that problem (i.e. String Theory).
Does this mean that Newton was wrong? No, certainly not. (If you put Newon’s numbers/calculations into Einstein’s, they work.) The truth of the Laws of Motion didn’t change because Einstein brought us a deeper understanding. And Einstein won’t become wrong when the workings of the singularity at the center of a black hole are explained.
There is absolute truth in this world. In fact, without absolute truth, when everything becomes relative, all things become permissible. (This explains, in part, why dictatorship regimes seek to rid the society of religion or turn the regime into the religion.)
What does this have to do with serving your communities, your schools, and your classrooms? Your vision, your strategic plans, and your goals and objectives are meaningless unless you help people feel and see that they are a part of something bigger than themselves. You have to connect them to that truth. If you don’t know what you stand for, you stand for nothing. If you try to be all things to all people, you can’t possibly be successful.
