Lest any root of bitterness springing up trouble you, and thereby many be defiled.
Bitterness! How it eats away inside you and destroys your happiness, makes you impossible to get along with and eventually destroys the bond of fellowship with those near you. A bitter spirit not only destroys you, but also many others with whom you come in contact. If you have a bitter feeling towards anyone, you need to get it corrected. Go and talk to the one about whom you have bad thoughts. It may only be a tiny root, but, if not dealt with, it will grow into a massive weed that will have dramatic and devastating results.
