It begins as a tiny seed, but then grows and eventually consumes its host.
The Bitter Root.
That’s what the anonymous author of the Epistle to the Hebrews warned against in Heb. 12: 15: for it “defiles (taints) every relationship” ( including the one with God).
Yes, the Bitter Root begins as a tiny seed of resentment. Someone says and/or does something that wounds us. At first, we try to ignore it or slough it off; however, unless quickly dealt with, it burrows down deep into our memory.
Soon, it transfers to the “hotbed of the heart” where it begins putting down feeler roots. The more we think or talk about it our hurt, the deeper the roots begin to grow. Then, the taproot begins to grow downward while also growing upward. And, before long it begins producing bitter fruit in the form of criticism, backbiting, slander and sarcasm.
So, the question is “What causes this to happen?”
