Paul continues his teaching about the return of Christ. He explains that the day of the Lord will come suddenly and unexpectedly, like a thief in the night. Believers, however, should not be caught off guard because they live in the light and should stay awake, alert, and self-controlled, clothed with faith, love, and hope of salvation. God has destined them not for wrath but for salvation through Jesus, who died so they may live with Him.
Paul then gives practical instructions for Christian living:
Encourage, help, and build up one another.
Respect leaders who work hard among them.
Be patient with everyone, avoid revenge, and always pursue goodness.
Rejoice always, pray continually, and give thanks in all circumstances.
Do not quench the Spirit, despise prophecies, or accept evil—but test everything and hold onto what is good.
He closes with a prayer that God will sanctify them completely in spirit, soul, and body until Christ’s coming, assuring them that God is faithful to accomplish it. Paul asks for their prayers, urges them to greet one another warmly, and insists that his letter be read to all believers, ending with a blessing of grace.
