I saw a very amusing post on Facebook the other day. It said something along the lines of, "Inside every old person is a young person, wondering what the heck happened!" I could relate to this. They say the older you get, the faster life speeds by and, as a 60-something, I can vouch for this.
My grey hairs are being judiciously covered up with the right chemicals on a regular basis but we can't stop the march of time. We are all programmed to get old and this life won't last forever, but remember that Jesus offers you eternal life if you believe in Him and accept what He has done for you.
