As we age, our physical condition deteriorates and there's not much we can do about it. Our mental capacity remains pretty much constant, then weakens too over time. But the potential to grow spiritually for us is practically limitless, for we can submit to God to let him make us as holy as we wish. ln fact, this is what we should concentrate upon primarily, besides going to the gym and exercising our minds. The everlasting soul is infinitely more important than the passing body. In giving it the best attention, we are getting ourselves ready for eternity!
