Some anger can be self-inflicted, brought on by your own actions and wrong decisions.
"You want to feel loved and accepted," says Dr. Les Carter. "As a result, you may find yourself more susceptible to sexual acting out, or maybe you have started hanging around a more unsavory crowd and engaging in social activities you might never have done before. These actions result in 'self-inflicted wounds,' which can later cause you to feel anger because you have a neediness that is pushing you to live in ways that you normally wouldn't choose."
When you give in to sexual or other temptations, your pain is numbed for a short time, but you remember what you did for a long time, and it can make you angry. If you have already given in to temptation and are feeling guilty or angry, stop. There is no need to dwell on what has been done. Turn to God for forgiveness and forgive yourself.
When you ask God to forgive a sin, He forgives you thoroughly. This is extremely difficult for our human nature to comprehend, as we like to remember and rehash things in our minds. God's Word says there is "no condemnation" for those who seek forgiveness through Jesus Christ. You must be an imitator of Christ and stop blaming yourself when you have already been forgiven. God is not pleased with self-condemnation because that is not how He taught us to behave.
"Therefore, there is now no condemnation for those who are in Christ Jesus, because through Christ Jesus the law of the Spirit of life set me free from the law of sin and death" (Romans 8:1-2).
