“The poisonous weed of bitterness thrives in the deep soil of unresolved anger.

It must be pulled up by its roots, not just snipped off at the top.

Hebrews 12:15 states that a root of bitterness can spring up and cause trouble, causing many to be defiled. You cannot nurture the bitterness plant and at the same time keep it concealed. The bitter root bears bitter fruit. You may think you can hide it … live with it … grin and bear it, but you cannot. Slowly, inexorably, that sharp, cutting edge of unforgiveness will work its way to the surface. The poison seedling will find insidious ways to cut into others. Ironically, the one who suffers most is the one who lashes out at those around him. He becomes victim of the giant he refused to slay.”—Charles R. Swindoll, Killing Giants, Pulling Thorns (Grand Rapids, Mich.: Zondervan Publishing House, 1994), pp. 26–27.
