"What does the Bible say about Christian character?"

Character is defined as strength of moral fiber. A.W. Tozer described character as “the excellence of moral beings.” As the excellence of gold is its purity and the excellence of art is its beauty, so the excellence of man is his character. Persons of character are noted for their honesty, ethics, and charity. Descriptions such as “man of principle” and “woman of integrity” are assertions of character. A lack of character is moral deficiency, and persons lacking character tend to behave dishonestly, unethically, and uncharitably.

A person’s character is the sum of his or her disposition, thoughts, intentions, desires, and actions. It is good to remember that character is gauged by general tendencies, not on the basis of a few isolated actions. We must look at the whole life. For example, King David was a man of good character (1 Samuel 13:14) although he sinned on occasion (2 Samuel 11). And although King Ahab may have acted nobly once (1 Kings 22:35), he was still a man of overall bad character (1 Kings 16:33). Several people in the Bible are described as having noble character: Ruth (Ruth 3:11), Hanani (Nehemiah 7:2), David (Psalm 78:72), and Job (Job 2:3). These individuals’ lives were distinguished by persistent moral virtue.

Character is influenced and developed by our choices. Daniel “resolved not to defile himself” in Babylon (Daniel 1:8), and that godly choice was an important step in formulating an unassailable integrity in the young man’s life. Character, in turn, influences our choices. “The integrity of the upright guides them” (Proverbs 11:3a). Character will help us weather the storms of life and keep us from sin (Proverbs 10:9a).

It is the Lord’s purpose to develop character within us. “The crucible for silver and the furnace for gold, but the LORD tests the heart” (Proverbs 17:3). Godly character is the result of the Holy Spirit’s work of sanctification. Character in the believer is a consistent manifestation of Jesus in his life. It is the purity of heart that God gives becoming purity in action. God sometimes uses trials to strengthen character: “we also rejoice in our sufferings, because we know that suffering produces perseverance; perseverance, character; and character, hope” (Romans 5:3-4). The Lord is pleased when His children grow in character. “You test the heart and are pleased with integrity” (1 Chronicles 29:17; see also Psalm 15:1-2).

We can develop character by controlling our thoughts (Philippians 4:8), practicing Christian virtues (2 Peter 1:5-6), guarding our hearts (Proverbs 4:23; Matthew 15:18-20), and keeping good company (1 Corinthians 15:33). Men and women of character will set a good example for others to follow, and their godly reputation will be evident to all (Titus 2:7-8).
