It also means any bitter, unpleasant or mortifying experience. The root of bitterness and the root that beareth gall and wormwood are connected. The problem with bitterness is that instead of hurting the one whom you are bitter against, you are the one that suffers, Bitterness will literally make you sick in body, much less in spirit. Perhaps the experience that has made us so very bitter is one that God allowed in our life to make us tender. God cannot plant in hard, dry ground.
Some folks never get over a bitter experience.
They relive it over and over in their minds instead of letting the Lord give them peace and being broken. It is of the LORD'S mercies that we are not consumed, because his compassions fail not. When the Lord plants His seed in our hearts, it's His desire for us to be fruitfull. I'm sure it is a great sorrow to His heart to see our hearts choked with the weeds of the world, the thorns of bad relationships and the roots of bitterness. Tenn.
