2 Thessalonians 2:13-17 - Stand Firm And Hold Fast
13 We ought always to be thanking God for you, brothers dearly loved by the Lord, because God chose you from the beginning for salvation through the Spirit's consecration of you and through your faith in the truth, 14 and to this end He called you by our preaching of the good news, so that you may obtain the glory of our Lord Jesus Christ. 15 So then, brothers, continue to stand firm and keep a tight grip on the teachings you have received from us, whether by word of mouth or by letter.
16 May our Lord Jesus Christ Himself and God our Father, who has loved us and graciously given us encouragement that is eternal, and a hope that is well-founded, 17 encourage your hearts and strengthen you in every good thing you do or say.
