Ephesians 4:26 New King James Version || “Be angry, and do not sin”: do not let the sun go down on your wrath,
God’s elect, anger is a natural thing embedded in the life of a man (generic) but it has to be controlled by the indwelling of the Holy Spirit in us. Our life is now owned by God through Christ Jesus by the Precious Holy Spirit. God is the creator of the universe, man inclusive, He sends Christ Jesus to come and die for man for his redemption and reconciliation, after the fall or the separation from God, Christ Jesus leaves the earth, and He sends another kind of Himself to be with the Saints (believers), which is the Holy Ghost.
This is why anytime you want to do something; you will hear an inner voice in your heart, either to do or not to do, either to agree or to disagree: please that is never your conscience talking to you as a child of God, but God talking to your heart in the Name of Jesus, through the Holy Ghost on what to do, how and when to do it.
Because of the above explanation from the scriptures, you can get angry alright, but it should never make you sin, the sun shall not go down on your anger; this means, day should not break on your anger. This is why you need to ask the Holy Ghost in the Name of Jesus, for wisdom to be able to live with people if only you want to please God.
Prayer
In the Name of Christ Jesus, I ask for the wisdom to be able to live with man, and that the sun should not set on my anger, amen!
