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;
It is, also, not without good reason, that he says with power, for he intimates that the perfecting of faith is an arduous matter, and one of the greatest difficulty. This, also, we know but too well from experience; and the reason, too, is not far to seek, if we consider how great our weakness is, how various are the hindrances that obstruct us on every side, and how severe are the assaults of Satan. Hence, unless the power of God afford us help in no ordinary degree, faith will never rise to its full height. For it is no easier task to bring faith to perfection in an individual, than to rear upon water a tower that may by its firmness withstand all storms and fury of tempests, and may surmount the clouds in height, for we are not less fluid than water, and it is necessary that the height of faith reach as high as heaven.
