What Does the Bible Say about Bitterness and Resentment? by CBN.com
When you are offended or disappointed by others and allow the hurt to germinate in your heart, bitterness and resentment will take root. Characterized by an unforgiving spirit and generally negative, critical attitudes, bitterness and resentment are sinful and self-defeating. They will color your conscious and unconscious thoughts and actions. Allowed to fester, they will destroy and kill (Galatians 5:19-21). However, they can be dispelled with love.
What Scripture Says
“Make every effort to live in peace with all men and to be holy; without holiness no one will see the Lord. See to it that no one misses the grace of God and that no bitter root grows up to cause trouble and defile many” (Hebrews 12:14,15).
“Get rid of all bitterness, rage, and anger, brawling and slander, along with every form of malice. Be kind and compassionate to one another, forgiving each other, just as in Christ God forgave you” (Ephesians 4:31,32).
“When they hurled their insults at him, he did not retaliate; when he suffered, he made no threats. Instead, he entrusted himself to him who judges justly” (1 Peter 2:23).
“Jesus said, Father, forgive them, for they do not know what they are doing…” (Luke 23:34).
“For if you forgive men when they sin against you, your heavenly Father will also forgive you. But if you do not forgive men their sins, your Father will not forgive your sins” (Matthew 6:14,15).
“Bless those who persecute you; bless and do not curse. Rejoice with those who rejoice; mourn with those who mourn. Live in harmony with one another. Do not be proud, but be willing to associate with people of low position. Do not be conceited. Do not repay anyone evil for evil. Be careful to do what is right in the eyes of everybody. If it is possible, as far as it depends on you, live at peace with everyone. Do not take revenge, my friends, but leave room for God’s wrath, for it is written: ‘It is mine to avenge; I will repay,’ says the Lord. On the contrary: ‘If your enemy is hungry, feed him; if he is thirsty, give him something to drink. In doing this, you will heap burning coals on his head.’ Do not be overcome by evil, but overcome evil with good” (Romans 12:14-21).
