How should Christians deal with anger according to the Bible?

Ephesians 4:26 nuances how Christians should approach anger, stating, 'Be ye angry and sin not.' This acknowledges that anger itself is not inherently sinful; rather, it's the response to that anger that matters. Righteous anger, according to scripture, is a response to injustices and sin, akin to God's own anger towards sin. However, believers are warned against allowing anger to fester into bitterness or unresolved conflict, as this invites division and opportunity for the devil (Ephesians 4:27). It is crucial for Christians to resolve anger quickly and not allow it to lead to sin, promoting reconciliation and peace instead. This reflective practice enables them to maintain unity and reflects the character of Christ in their relationships.
