To this end we also pray always for you, that our God may count you worthy of your calling, and fulfill every desire of goodness and work of faith, with power;
The idea being presented is that just as through God’s grace the Thessalonians were led to obedience His grace would "make (them) worthy" of their call. In verse 3, Paul speaks of the words of thanks he offers to the Lord for the growing faith of the Thessalonians. Now he prays (proseuchomai) ("signifies a petition" Kittel, Vol. II 807) that God will consider them worthy of their call to Christianity. Our prayers today should be the same.
