There are expiration dates on almost everything these days: milk, cheese, chips, dressings, meats, even sodas (pop), and cookies. What do these dates mean exactly? There is the "best if used by date" which means that the product is still edible but may not taste as good. Or you must "use by" this date if the manufacturer will vouch for it. Finally, there is the "sell by" date; don't buy the product after this date. This is the final "expiration" date.
Like you, there is no expiration date stamped on the bottom of my foot or across my forehead that tells me or proclaims when my life will end. When a patient has a life threatening or terminal illness, some doctors will try to predict how much time they have left. "You only have three months to live" or "You have less than a year." There is only One who knows that information.
Many people contemplate their own mortality at some point in their life. Some people live each day as if it is their last. They keep their finances in order, tell their family and friends how much they are loved, and keep their "bucket list" short or complete. On the opposite side, people pass through life like they will never die. The put off taking care of things because there is always tomorrow.
There is no doubt that my physical body will expire and so will yours. It's simply a matter of when. But our spiritual body truly has no expiration date. That spiritual body will spend eternity somewhere. The choice is ours as to where we spend it.
If you don't know Jesus, have put off accepting His gift of salvation, or want to rededicate your life, today, This Day, is the day. For those who accept Jesus as their Lord and Savior, eternity is a mansion in heaven. How do I know? Jesus told me so.
Peace and Joy,
