A friend of mine went through a massive emotional breakdown. After his recovery, we went for a walk. "Luis," he told me, "don't ever allow anyone to make you bitter."
He told me about his breakdown which proved very embarrassing.

"My problems began when I got so worked up about the contractor who didn't build my basement and driveway right. I hated what he'd done to my home. And since he lived next door, I saw him almost daily. Each time I saw him, my anger and bitterness grew even more intense until I finally cracked."

No wonder God's Word is so emphatic: "Get rid of all bitterness" (Ephesians 4:31). Why? Because if a "bitter root grows up" within you, it will "cause trouble and defile many" (Hebrews 12:15).
