2 Thessalonians 2:13-17 (NASB)
13  But we should always give thanks to God for you, brethren beloved by the Lord, because God has chosen you from the beginning for salvation  through sanctification by the Spirit and faith in the truth.  14  It was for this He called you through our gospel, that you may gain the glory of our Lord Jesus Christ.  15  So then, brethren, stand firm and hold to the traditions which you were taught, whether by word of mouth or by letter from us.
16  Now may our Lord Jesus Christ Himself and God our Father, who has loved us and given us eternal comfort and good hope by grace,  17  comfort and strengthen your hearts in every good work and word.
