We are bound to always give thanks to God for you, brothers,{The word for "brothers" here and where context allows may also be correctly translated "brothers and sisters" or "siblings."} even as it is appropriate, because your faith grows exceedingly, and the love of each and every one of you towards one another abounds;
Paul seems to have felt a special debt of gratitude to God for the grace given to the Thessalonians, the grace that has caused them to stand true to the faith during a time of suffering and anguish. Thanksgiving is not only an expression the writers feel they owe to God; they assure the readers they deserve the commendation.
