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;
And so Paul, giving thanks unto God. He felt it was necessary to give thanks to God for two very positive traits and characteristics in this church. One, their faith was growing exceedingly. Secondly, their love for all of the brethren was just abounding. What tremendous characteristics to mark a church, a church of great faith and a church where God's love among the people was just abounding.
