Only God judges righteously. Jesus likened the condition of our hearts to that of soil. Ground will produce only what is planted in it. If we plant seeds of debt, unforgiving-ness, and offense, another root will spring up called the root of bitterness . It is produced when revenge is not satisfied to the degree we desire.
Bitterness is a root.
If watered, protected, fed, and given attention, it will increase in depth and strength. If not dealt with quickly roots are hard to pull up. The strength of the offense will continue to grow. Instead of the fruit of righteousness, we will see a harvest of anger, resentment, jealousy, hatred, strife, and discord. A person who does not pursue peace by releasing offenses will eventually become defiled.
