People sometimes speak about grace and holiness as though one must displace the other. Titus 2:11-14 brings them together in a single passage. Paul says that the grace of God has appeared, bringing salvation, and that this grace trains people to turn away from ungodliness and to live with self-control, righteousness and godliness. The passage locates Christian conduct in what God has done and in the hope of Christ's appearing. It is not a claim that believers transform themselves by collecting strict rules.
Read the whole second chapter of Titus before narrowing your attention to these verses. Paul is addressing a community with different ages and responsibilities. The instruction concerns truthful speech, faithfulness and conduct that honors the teaching about God. It reaches into habits, relationships and daily work. The passage also names Jesus Christ as the one who gave himself to redeem and purify a people eager to do good. Christian obedience is therefore connected to the person and work of Christ, not to a contest over religious appearances.
A useful question is not simply, 'What behavior should I stop?' Ask also, 'What good does this passage call me to practice?' Consider patience, honesty, service and self-control in the setting where you already live. Then read Titus 3:3-8, where mercy and the renewal associated with the Holy Spirit are placed beside a call to good works. Let the two chapters interpret one another. This short reading can begin a longer study, but it cannot replace the larger letter.
