What does the Bible teach about Christian character and conduct?

Analysis

The fruit of the Spirit, Galatians 5:22-23

Paul contrasts two ways of living. The "works of the flesh" (Galatians 5:19-21) versus the fruit (singular, one integrated character) of the Spirit:

"But the fruit of the Spirit is love, joy, peace, patience, kindness, goodness, faithfulness, gentleness, and self-control. Against such things there is no law.", Galatians 5:22-23 (WEB)

The sanctification synthesis identifies Galatians 5:16-25 as a foundational text: walk by the Spirit; works of the flesh vs. fruit of the Spirit.

Christian character from the inside out, the Beatitudes (Matthew 5:1-12)

Jesus opens the Sermon on the Mount by describing the character of those who belong to the kingdom:

Jesus then turns character into public conduct: kingdom people are "salt of the earth" and "light of the world" whose "good works" lead others to glorify God (Matthew 5:13-16), and whose righteousness must … (Matthew 5:20), i.e., real, heart-deep, not merely external. Nave's Topical Bible explicitly lists the Beatitudes as marks of the saints' character ("Hungering for righteousness Matthew 5:6," "Meek Matthew 5:5," "Merciful Matthew 5:7," "Pure in heart Matthew 5:8," "Poor in spirit Matthew 5:3") (Nave's, CHARACTER).

Character translated into conduct, Colossians 3:12-17

Colossians 3 gives the "take off / put on" pattern. Believers "put to death" the old conduct (Colossians 3:5-9) and "put on" the new:

"Put on therefore, as God's chosen ones, holy and beloved, a heart of compassion, kindness, lowliness, humility, and perseverance; bearing with one another, and forgiving each other… Above all these things, walk in love, which is the bond of perfection.", Colossians 3:12-14

The passage then covers concrete conduct: let Christ's peace rule, his word dwell richly, teach + admonish one another, and "whatever you do, in word or in deed, do all in the name of the Lord Jesus" (Colossians 3:16-17). Character (compassion, humility) becomes conduct (forgiving, teaching, doing everything for Christ).

The summary verse, Micah 6:8

The Old Testament distills the whole ethic into one line:

"He has shown you, O man, what is good. What does Yahweh require of you, but to act justly, to love mercy, and to walk humbly with your God?", Micah 6:8

Nave's files Micah 6:8 under HOLINESS (Nave's, HOLINESS), tying personal ethics to holiness.

The growth chain, 2 Peter 1:5-8

Peter presents character as an additive, growing sequence, virtues built upon faith:

"Yes, and for this very cause adding on your part all diligence, in your faith supply moral excellence; and in moral excellence, knowledge; and in knowledge, self-control; and in self-control, perseverance; and in perseverance, godliness; and in godliness, brotherly affection; and in brotherly affection, love.", 2 Peter 1:5-7

The result: … (2 Peter 1:8). Christian character is not static, it is cultivated and grows.

The engine underneath, Romans 12 (transformation, not conformity)

Romans 12 shows how and why the conduct flows:

• The basis: "present your bodies a living sacrifice… do not be conformed to this world, but be transformed by the renewing of your mind" (Romans 12:1-2). Conduct begins with a transformed identity + mind.
• The conduct: love without hypocrisy, honor one another, serve the Lord, contribute to the needs of the saints, bless persecutors, "overcome evil with good" (Romans 12:9-21).

This is the crucial theological point this reference emphasizes: biblical character/conduct is the fruit of God's transforming work, …. It is grace producing godliness, not godliness earning grace.

How it all fits together

Where traditions differ (multi-view)

The texts above are not contested, but how far character can be perfected in this life, and the relationship of these "good works" to salvation, connects to the sanctification debate. These are presented neutrally, endorsing none:
