@emil01. The root of bitterness is one of the biggest causes why many people are in misery, sick, and even, separated from God. It is stronger than the lack of forgiveness, since it develops roots with it, such as anger, anger and slander. Bitterness is an anguish of the soul; It is a resentment, it is like a poison that contaminates the heart and makes us forget all good work that God and people have done for us. As Christians we must avoid this evil and if we meet someone in this way ask wisdom to God to be able to deal with and alleviate their attitude with the word of God.
