Plato and Aristotle taught us that every human being crave and desire deep inside them to attain things that are infinite - Love, Goodness, Truth and Beauty. According to our Christian theology, these Infinite qualities are God Himself.
Most of us, we are unable to fathom what infinity or everlasting means. We just cannot comprehend how infinity or everlasting would be like - especially since we always use our current life on earth as our reference point. Let me make an effort to get you thinking in that direction.
Think about that last beach you visited with your family and friends. Of course you noticed those sand particles under your feet, stretching out for miles and miles. You were standing safe - away from those tides and water.
Now imagine you standing at that very same beach - this time you are all alone. Notice a beautiful blue bird flying towards that beach. It lands near you, picks up one speck of sand and flies off. One million years later, the bird returns and you recognize the same beautiful bird. She now picks up another grain of sand near your feet, from the same beach you are standing at. With the second grain of sand in her beak, she flies off for another one million years.
After several million years, you are still standing at that beach and realize what the bird is upto. She is trying to clean up the beach, one grain of sand at a time, at a rate of one million years per grain. Eventually, at some point in time, she will be successful in clearing off those entire sand particles at the beach you are standing at.
After having successfully completed her task at your favorite beach, she then has bigger plans. She moves on to clear every sand particle from every beach in the world, at the same rate of one million years per sand particle. She will be successful in her pursuit to do so - at some point in time after gazillion years.
Once the lovely little bird has cleared off every sand particle from every beach on earth, she still does not stop to take rest. As your curiosity increases, you notice the little bird now has a different plan - she is returning with a speck of sand to the beach where she started her activity, and she takes one million years to return with that second sand particle.
After gazillion million years, she would have replenished all those sand particles on all those beaches on our entire earth. At this instance if you were to check what time it was in heaven, you would notice that not even a single day has transpired in heaven all this time. There are many many uncountable heavenly years ahead of you to enjoy with the Creator!!
Isaiah 40:28 - “Do you not know? Have you not heard? The Lord is the everlasting God, the Creator of the ends of the earth, He will not grow tired or weary and his understanding no one can fathom.”Now you get an idea about everlasting?
Hey, you've been standing on that beach for so long - now come inside eat something, and get some rest.
