When the grand babies arrive, it's an entirely the same but in its own special way. You get to see your children's reactions to their child's birth and from the outside see them in that moment that amazing love be realized, in addition of the love you once again feel as if you were having your children all over again. With grand children, you are generally gained experience from raising your children and hopefully, from that experience are less likely to let the little things that you use to think were important, stressed about, building a career, etc. You realize that's what important is time. That time is a precious gift that has a shelf life. The date is not stamped anywhere, but you have discovered that it's but a fleeting moment, a flash of light, a blink of the eye. Just as you can't tell what love truly feels like, neither can you teach that our days are long, but our time is short.
Just as Jesus taught 2000 years ago "Three things will last forever--faith, hope, and love--and the greatest of these is love." As much as we love our children and grandchildren, I often think how much more does my father in heaven, who created me with His hands, who created the earth and all of its stars and universes. He created all the animals, everything. I can't begin to fathom the He has for His creations. His children. I am blessed!
