Therefore they are to stand firm and hold to the teachings delivered by speech or letter.
What it is doing
It turns thanksgiving into a call for steadiness.
In context
13But we should always thank God for you, brothers who are loved by the Lord, because God chose you from the beginning to be saved by the sanctification of the Spirit and by faith in the truth. 14To this He called you through our gospel, so that you may share in the glory of our Lord Jesus Christ. 15Therefore, brothers, stand firm and cling to the traditions we taught you, whether by speech or by letter. 16Now may our Lord Jesus Christ Himself and God our Father, who by grace has loved us and given us eternal comfort and good hope, 17encourage your hearts and strengthen you in every good word and deed.
