Bitterness and Forgiving others.

How to be set free from the spirit of Bitterness and not forgiving others?  The word of God states in  Hebrews 12:¹⁵ looking carefully lest anyone fall short of the grace of God; lest any root of bitterness springing up cause trouble, and by this many become defiled".

When we read Ephesians 4:31-52 in the text we are guided to get rid of all bitterness.  Jesus Christ died on the cross for our sins and transgressions.  Today bitterness and having an unforgiving spirit is the primary illness and infirmity.  Tune in an educate yourself and then activate the word of God.
