I am walking home from work. I take a step, then another, then another. Each step takes x amount of time. Time from our mortal finite perspective only goes forward. A nano-second gone by can not be recovered.
Science can not explain why we die. It can observe we die from auto accidents, cancer, or by means of homicide, or what ever. Science can only observe that we die, but does not explain why we get older, weaker, slower, more and more feeble, and at some point or another we physically expire. Science can only observe and describe the process. It can not explain why the process happens.
So we step through this mortal life to the end, and then eternity. The same with breathing. Breath in. Breath out. Nano-seconds of our life flying by never to be recovered. In... Out... In... Out... Step. Step. Stepping towards eternity...
How many non-seconds are you closer to eternity since you first started to read this?
Some think eternity is oblivion. We die and that's it. Others see eternity as a cosmic Merry-go-round, as we take various forms and shapes whirling around on some great mandela. The Bible says it is appointed unto man once to die, then the judgment. The Bible points to the resurrection from the dead, and the new heavens and new earth. The Bible also talks about hell.
Step by step. Step by step. Step by step towards eternity, not knowing at what un-escapable moment we will take that last step... That last step into eternity. Are you ready?
