No matter how much we know or how well we think we know something, there is always room for improvement. That is the biggest room that exists it seems. We cannot completely fill this room.
The fun of life is in knowing that there are better ways and deeper areas of understanding that constantly lie ahead of us. We need not become stale or bored with life. In a sense, mankind has only scratched the surface of all knowledge and not even gotten through the “peeling of the apple.” God’s thoughts and ways exceed ours like the universe exceeds the earth. We have a long and wonderful trip ahead of us.
