Looking diligently lest any man fail of the grace of God;
lest any root of bitterness springing up trouble you, and thereby many be defiled.
Hebrews 12:15
"Bitterness and a bitter spirit should never characterize a person who has experienced the saving grace of God through Jesus Christ. No matter how seriously one may have been wronged.
Bitterness is a characteristic of the ungodly “whose mouth is full of cursing and
bitterness” (Romans 3:14).
“If ye have bitter envying and strife in your hearts, glory not, and lie not against the truth. This wisdom descendeth not from above, but is earthly, sensual, devilish” (James 3:14-15). Rooted bitterness will soon “spring up,” not only robbing the bitter believer of joy and true fruitfulness, but bearing bitter fruit whereby many others will “be defiled.”
Therefore, “let all bitterness, and wrath, and anger, and clamor, and evil speaking, be put away from you, with all malice: And be ye kind one to another, tenderhearted, forgiving one another, even as God for Christ’s sake hath forgiven you” (Ephesians 4:31-32). Otherwise, we not only hurt both ourselves and others, but we also grieve “the holy Spirit of God” (v. 30)."
