Now you yourselves are to put off all these: anger, wrath, malice, blasphemy, filthy language out of your mouth. Colossians 3:8 (NKJV)
Some boundary markers on handling volatile emotions include the following:
(1) Deal directly with the situation or responsible party who has irked you. Face conflict head-on. Refuse to spread your anger to other parties.
(2) Resolve your anger as quickly as possible under the leadership of the Holy Spirit. It is folly to let your anger brew over days, weeks, or months. That is the perfect breeding ground for bitterness and division.
(3) Remember that the temperament and personality of other people can easily provoke you. If this is the catalyst that makes you angry, your best choice is to accept others as God accepts you—freely and unconditionally.
(4) Make a daily choice to submit to the reign of the Holy Spirit in your emotional life. Put your focus on Christ and the peace He gives in all circumstances. The sweeter your fellowship with Jesus, the more like Him you will naturally become with the Spirit’s help.
