I was in the middle of a haircut the other day and we got to talking about Alzheimers and dementia when my pastor/boss mentioned that he had watched a documentary about Alzheimers where they said that it was the brain hardening. The Alzheimers Association website says that there are “Two abnormal structures called plaques and tangles [that] are [the] prime suspects in damaging and killing nerve cells” in the brain. They say that “Plaques are deposits of a protein fragment called beta-amyloid (BAY-tuh AM-uh-loyd) that build up in the spaces between nerve cells” and “Tangles are twisted fibers of another protein called tau (rhymes with “wow”) that build up inside cells.”
But as my pastor shared this with me it got my mind going. A couple of weeks ago my dear friend Chris Tilling ably demonstrated that the New Testament doesn’t make the distinction between head and heart that many people think it does. In fact, when Scripture speaks of the heart it usually, if not always, has the thought life in view. Hebrews 3:8 immediately came to mind, which says, “do not harden your hearts as in the rebellion, on the day of testing in the wilderness.” I suggested that perhaps something like Alzheimers was going on with the Israelites as they wandered those 40 years in the desert.
Think about it, God has to constantly remind them of who he was and what he had done. He constantly told them that he was the LORD their God who had brought them out of the land of Egypt. They clearly couldn’t remember his commandments, which is why he had to keep reminding them about his laws and statutes. If in fact this hardening of the heart was a hardening of the mind, which many believe to be seated in the brain, then is it so far fetched to think that there really could have been plaques and tangles at play? It’s definitely something to ponder and I’ll post something else on this with regard to some of the statements made about hardened hearts in the NT.
