B is for Bitterness

Holding on to bitterness can mean big trouble. I know this from my own experience. That's when we need to support one another...

Look after each other so that not one of you will fail to find God's best blessings. Watch out that no bitterness takes root among you, for as it springs up it causes deep trouble, hurting many in their spiritual lives.

Hebrews 12:15, TLB.
