Jealousy is an emotion that is fed by unclean thought.
Those who would serve the King can not afford this spiritual cancer. Jealousy wants harm to come to the object of the jealousy and nothing can satisfy the craving. If not checked, jealousy will create its own universe in the soul.
Jealousy is a sin and must be confessed. There must be clean prayer about the matter and it must be left with the Lord. There can be no fellowship with Him, as long as there is an agenda against another.
Soldier, walk with clean and empty hands.
