We all want to live. Some people want to live forever. There are people out there that would do anything to live in their mortal body, forever young and healthy, but that is not possible because the world is also dying. I am more specific- I want to live forever in a perfectly healthy world and body. I don't want to live in this mortal body that decays more every year and is destined to die? To me, it is foolish to want to live forever in this dying world even if we are perfectly healthy.
There are other things I think that are foolish: spending more money than you have, not listening to the advice of many counselors, thinking that man knows more than his Creator, etc. If you want to know how to be wise, there are many Scriptures that can help with that and Proverbs is full of wisdom vs. foolishness and so is a great place to learn more about it. Here is one prime example.
Forsake the foolish and live; and go in the way of understanding.
The fear of Jehovah is the beginning of wisdom; and the knowledge of the holy is understanding. Pr. 9:6,10
The fear of Jehovah is the beginning of wisdom; and the knowledge of the holy is understanding. Pr. 9:6,10
It is important to understand the logic in these two verses. To live, you must forsake being foolish and must walk in understanding. How do we live in understanding? Fear God to start being wise, and have the knowledge, perception and discernment of the holy (meaning sacred, Holy One). So, understanding is found in the knowledge of God. The more we understand Him, the more we understand all things and the more wise we become.
So basically we need to forsake the foolishness of man, and go in the way of God. Seems easy enough to me. God is our Creator and if we want to understand anything, He is the only one with all the answers- and we need to seek Him.
