Know this, my beloved brothers: let every person be quick to hear, slow to speak, slow to anger; for the anger of man does not produce the righteousness of God. Therefore put away all filthiness and rampant wickedness and receive with meekness the implanted word, which is able to save your souls.
But be doers of the word, and not hearers only, deceiving yourselves. For if anyone is a hearer of the word and not a doer, he is like a man who looks intently at his natural face in a mirror. For he looks at himself and goes away and at once forgets what he was like. But the one who looks into the perfect law, the law of liberty, and perseveres, being no hearer who forgets but a doer who acts, he will be blessed in his doing. If anyone thinks he is religious and does not bridle his tongue but deceives his heart, this person’s religion is worthless. Religion that is pure and undefiled before God, the Father, is this: to visit orphans and widows in their affliction, and to keep oneself unstained from the world. ~James 1:19-27
Most anger is a fleshly anger, an anger produced of man not of the righteousness of God. The point I want to bring out is being a doer of the Word also includes being quick to hear (Proverbs 18:13) and being slow to anger (Proverbs 14:29), as well as, bridling the tongue (Proverbs 12:23; Proverbs 13:16; Proverbs 15:2; Proverbs 15:14). Visiting orphans and widows in their affliction does not outweigh the folly of allowing anger to flourish and the tongue to be unbridled (Proverbs 17:12; Ecclesiastes 10:1).
Other passages to note:
If anyone says, ‘I love God,’ and hates his brother, he is a liar; for he who does not love his brother whom he has seen cannot love God whom he has not seen. 21 And this commandment we have from him: whoever loves God must also love his brother. ~1 John 4:20-21
“You have heard that it was said, ‘You shall love your neighbor and hate your enemy.’ But I say to you, Love your enemies and pray for those who persecute you, so that you may be sons of your Father who is in heaven. For he makes his sun rise on the evil and on the good, and sends rain on the just and on the unjust. For if you love those who love you, what reward do you have? Do not even the tax collectors do the same? And if you greet only your brothers, what more are you doing than others? Do not even the Gentiles do the same? You therefore must be perfect, as your heavenly Father is perfect. ~Matthew 5:43-48 (Luke 6:27-31)
But I say to you that everyone who is angry with his brother will be liable to judgment; whoever insults his brother will be liable to the council; and whoever says, ‘You fool!’ will be liable to the hell of fire. ~Matthew 5:22
from whom the whole body, joined and held together by every joint with which it is equipped, when each part is working properly, makes the body grow so that it builds itself up in love. … Therefore, having put away falsehood, let each one of you speak the truth with his neighbor, for we are members one of another. 26 Be angry and do not sin; do not let the sun go down on your anger, 27 and give no opportunity to the devil. ~Ephesians 4:16, 25-27
We must be a doer of the Word and not a hearer only. But if we do get angry, let not the sun go down on our anger; remember, “my little children, I am writing these things to you so that you may not sin. But if anyone does sin, we have an advocate with the Father, Jesus Christ the righteous. (1 John 2:1).
