What does Titus 3:15 mean?

This is the concluding verse of Paul's letter to Titus. First, Paul sends the love of the Christian church in Nicopolis to the fellow believers on Crete. This included Paul, Artemas, Tychicus, and other Christians.

Second, Paul says that this greeting is meant both for Titus and other believers throughout the island. This phrase is likely an encouragement to have the entire letter read in all of the local churches of Crete. Paul and Titus were the co-founders of the churches in Crete. And, Paul's writings were considered authoritative Scripture or authoritative by their readers (2 Peter 3:15–16).

Finally, Paul ends with his usual phrase, "Grace be with you all." If there was one word to summarize Paul's ministry, it was the word "grace." His salvation was the result of God's grace in his own life. Paul likewise sought to share this grace with Jews and Gentiles, even to the point of suffering as a criminal. In his final letter, Paul declares that even though he suffered imprisonment and persecution, God's Word could not be contained (2 Timothy 2:8–9).

Grace marked Paul's life, ministry, and even his death. Grace expresses Paul's eternal life, as a man who would be with Christ and forever, experiencing His grace in heaven alongside all of God's people.
