You breathe because it is profitable to your life.
You eat because it is profitable to your body to consume foodstuffs.
You drink because your body needs water – it is profitable to drink water.
You learn because you think what you are learning is profitable.
You work because it is profitable to do so.
You sleep on a regular basis because it is profitable to both mind and body.
For your health, safety, and welfare, your thoughts should be thoughts that are profitable. The only words throughout the ages that have been found to be always profitable are the words of God.
All Scripture is given by inspiration of God, and is profitable…2 Timothy 3:16.
Note that it is “all Scripture” that is profitable, not the words that people say about it. Scripture propagandists have been around as long as or longer than Government propagandists, and in many ways they have been much more successful.
