James 1:19-20

(19) Wherefore, my beloved brethren, let every man be swift to hear, slow to speak, slow to wrath: (20) For the wrath of man worketh not the righteousness of God.

God wants us to be quick and ready to hear Him and His truth. As disciples of Christ, we should always remember that we are engaged in learning from God the Father and Jesus Christ, and a good attitude is paramount in getting the most out of our lessons.

Being "slow to wrath" is learning to restrain our tempers and any wrong attitudes. Those that allow anger to trouble them have the tendency to break the law rather than keep it and to contend with ministers and brethren. When one allows wrath or a poor attitude into his thinking, doubts about God's instructions creep in, and disobedience often results. The wrath of man will not produce the right course of life and love of the truth that God requires.

The person who jumps to angry conclusions is often one who hears God's Word from the Bible but finds that it does not fit with his thinking or background. For whatever reason, he initially rejects what he hears. This is a hasty attitude, and it is one God does not like.

Proverbs 14:29: He who is slow to wrath has great understanding, but he who is impulsive [hasty of spirit, KJV] exalts folly.
Proverbs 21:5: The plans of the diligent lead surely to plenty, but those of everyone who is hasty, surely to poverty.
Proverbs 29:20: Do you see a man hasty in his words? There is more hope of a fool than for him.
Ecclesiastes 5:2: Do not be rash with your mouth, and let not your heart utter anything hastily before God. For God is in heaven, and you on the earth; therefore let your words be few.
