Titus 3 speaks about how Christians are instructed to submit to authority, show kindness and good deeds towards all people, and avoid divisive and foolish arguments. The chapter also emphasizes the importance of salvation and redemption through Jesus Christ, who saved us not because of our own righteous acts, but because of His mercy and grace. Paul encourages Titus to remind believers to be devoted to doing what is good and to avoid engaging in unproductive and useless debates. Finally, Paul closes with personal greetings and blessings for Titus and the believers with him.
