Unforgiveness and bitterness imprisons you from the inside. You may have heard of arteriosclerosis--"the hardening of the arteries"--which involves the hardening, thickening and the loss of elasticity in the walls of blood vessels. The disease develops over many years and results chiefly from the accumulation of fatty materials like cholesterol in the walls of the arteries. The smooth lining of the arteries become hard, narrow, and/or rough decreasing the flow of blood to the brain, the heart and limbs.
Unfortunately, ladies and gentlemen, it is possible to suffer a non-physical arteriosclerosis--a spiritual hardening of the arteries--where obstruction comes gradually. Resentment rises up and bitterness builds up--eventuating in a spiritual stroke. You become weak, paralyzed, immobile. The flow of friendship and the links of love are blocked. Both your head and heart are affected.
You need nothing short of a surgeon's knife--a spiritual by-pass surgery--to control the problem. And major surgery is always radical, but the divine doctor can make it a success.
