Anger is not sinful, yet the source of one’s anger sometimes does manifest one’s sinful heart. Perhaps the prophet Jonah best demonstrates this truth. When the Lord first approached Jonah about the need in Nineveh, Jonah clearly displayed his displeasure in seeing the Lord work in the lives of the Ninevites. After experiencing the Lord’s chastening, Jonah appeared to have a heart change. Yet, it did not take long before his anger revealed his true feelings and thoughts. As the hearts of the Ninevites were becoming tender toward the Lord, the prophet’s heart was becoming hardened through anger. His anger revealed that he wanted his own will and not God’s.
The Bible says that God is angry every day. Yet, at the same time He may display His anger, the Bible also says that He is love (1 John 4:8), and righteous (Ezra 9:15), and compassionate (Psalm 86:15), and just (Deuteronomy 32:4), and merciful (Deuteronomy 4:31). The source of God’s anger and the means by which He acts upon His anger sets the standard for what is truly a righteous anger. If man’s righteous acts provoked God to anger, this would signify a sinful nature. The Bible is clear that the opposite holds true. God is provoked to anger by sin (1 Kings 16:2), vanity (1 Kings 16:26), and idolatry (1 Kings 22:53). His righteous anger in each case plainly declares God’s righteous nature. The source of His anger sets forth the only sources by which men should become angry.
As opportunities present themselves, we ought to “do good” unto others. Scripturally speaking, we have a basic duty to help “all men,” but our foremost responsibility should be directed toward those “who are of the household of faith.” Regardless of our heart’s desire, the Lord knows there are times when we cannot help those in need. This fact should never be used as an excuse when we have a genuine opportunity, as the good that we might do to others does not always merely involve financial help. Acts chapter 3 offers an example of Peter and John who were faced with such a situation. Peter responded, “Silver and gold have I none; but such as I have give I thee” (Acts 3:6). Where these men lacked any monetary opportunity to help the lame man, they fulfilled their responsibility by imparting help in the way that God had especially enabled them.
