So then, brethren, stand firm and hold fast to the traditions and instructions which you were taught by us, whether by our word of mouth or by letter.

Now may our Lord Jesus Christ Himself and God our Father, Who loved us and gave us everlasting consolation and encouragement and well-founded hope through [His] grace (unmerited favor),

Comfort and encourage your hearts and strengthen them [make them steadfast and keep them unswerving] in every good work and word.
