“Let all bitterness and wrath and anger and clamor and slander be put away from you, along with all malice. Be kind to one another, tenderhearted, forgiving one another, as God in Christ forgave you.” (Eph 4:31-32)
I’m tempted to be bitter too often. Bitterness is a tool that helps me beat back pain, but it only makes it worse in the end, because it doesn’t address why the pain is there. When I screw up a relationship, I often want to be petty and bitter—it helps me avoid feeling despair. What it doesn’t do is address why I ended up in pain in the first place.
Bitterness is the alcoholism of the emotional realm. Don’t use it to try to feel better.
