This is a study on the Bible concept of bitterness. Bitterness is one of the most crushing mental problems in a person’s life. When a Christian is bitter, there is a loss of close fellowship with the Lord and a hindrance in one’s relationship with the Lord Jesus Christ. Bitterness causes a loss of many of the blessings of the normal Christian life, including emotional stability, peace, and joy. And pain results in the loss of production of good works (gold, silver, precious stones) which are a primary source of blessing and reward in the plan of God. Bitterness is neither consistent nor rational. A bitter person is his own worst enemy. It is challenging to maintain any relationship with a chronically angry person, and bitterness is a major contributing cause of marital and family problems?
