2 Thessalonians 2:13-15

As for us, we can’t help but thank God for you, dear brothers and sisters loved by the Lord. We are always thankful that God chose you to be among the first to experience salvation—a salvation that came through the Spirit who makes you holy and through your belief in the truth. He called you to salvation when we told you the Good News; now you can share in the glory of our Lord Jesus Christ. With all these things in mind, dear brothers and sisters, stand firm and keep a strong grip on the teaching we passed on to you both in person and by letter.
