Have you thought about eternity lately?
2 Cor 4:18
While we look not at the things which are seen, but at the things which are not seen: for the things which are seen are temporal; but the things which are not seen are eternal.
We live very close to two worlds....the physical and the spiritual. We understand the physical much more than we do the spiritual.
We can see the physical world but the spiritual world is not seen by the human eye.
In the physical world we can taste and touch and hear and smell and see.
And because those 5 senses are continuously being stimulated by the physical world...we have a greater understanding about that world.
We understand that there are laws in the physical world that control our lives.
