This is so true,anger is like addiction some people struggle with,all they need is to feed on Christ and his word because the gospel has the power to change them,and also see Jesus in his love and graciousness knowing that God is no longer angry with them because Christ has pay the price.2 Corinthians 3:18 But we all, with open face beholding as in a glass the glory of the Lord, are changed into the same image from glory to glory, even as by the Spirit of the LORD.
anger as an addiction - I didn't think of it that way, but you are right, some people are addicted to being angry.
