With anger being part of the emotional spheres of humans, I think we can all say that we've experienced intense anger at some point in our lives. Fortunately for us, it is an emotion we can learn to control. Proverbs 16:32 says, "He who is slow to anger is better than the mighty." When we are in control of anger, we allow the spirit of God to work in us, while impulsive and uncontrollable anger, deprives us of the Holy Spirit. Furthermore, this emotion, when not understood, can present itself in different ways, such as manipulation, promiscuity, self-harm, and so on. That being said, anger cannot be hidden; it will show itself one way or another (Matthew 7:17). The good news is that when we choose God, He reveals our most unpleasant characteristics and may use it for His glory.
His glory
If we focus on loving God, retaining His words, and following His commandments, our anger becomes a tool for Him to use. When we work on putting away the desire for control and pridefulness, which are two of the main reasons for anger, and instead put our passion behind the work that God commands us to do and set our minds on the things above (Colossians 3:2), the need to use anger outside of God becomes less and less each day. In addition, anger that is not outside of God is passion for the things of God. In Mark 3:5, Jesus's anger towards the Pharisees was out of love, like a parent disciplining their child that they love. Jesus was calling the Pharisees out of spiritual blindness and their hardened hearts, which grieved Him especially because they were considered Godly leaders. His reason for His anger was justified because they were going against the will of God, misleading others, and so His corrections were for righteousness' sake—for them to become spiritually right with God. It was for their good. Now, I'm not saying to use your anger to attack when preaching the word of God; I'm saying to go to Him as you are and allow Him to transform that anger into passion for His glory. And Lastly, continuously pray to Jesus about all of your concerns because He is the one who does the work in us. (Philippians 2:13).
Remember to seek first the kingdom of God, and everything else will be added to you (Matthew 6:33).
