Ephesians 4:31 - Let all bitterness, and wrath, and anger, and clamor, and evil speaking, be put away from you, with all malice:
Hebrews 12:15 - 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;
James 4:7 - Submit yourselves therefore to God. Resist the devil, and he will flee from you.
James 5:16 - Confess your faults one to another, and pray one for another, that ye may be healed. The effectual fervent prayer of a righteous man availeth much.
1 Peter 2:23 - Who, when he was reviled, reviled not again; when he suffered, he threatened not; but committed himself to him that judgeth righteously:
1 Peter 5:10 - But the God of all grace, who hath called us unto his eternal glory by Christ Jesus, after that ye have suffered a while, make you perfect, establish, strengthen, settle you.
