The chains of habit are too weak to be felt until they are too strong to be broken. (Samuel Johnson, 18th century English writer)
How do habits begin? You were taught to brush your teeth regularly and it soon became a regular activity that you rarely think about now. But how did it become your immediate response to react negatively or critically to something you hear or someone you meet before you have a more complete understanding? Beware of letting bad behavior become a habit.
Don’t copy the behavior and customs of this world, but let God transform you into a new person by changing the way you think (Romans 12:2).
