perfection brought about, not indeed by our remaining inactive and idle,[534] [but by some activity on our part]: and yet the consummation of it will not be ascribed to us, but to God, who is the first and chief cause of the work. So, when a ship has overcome the dangers of the sea, although the result be accomplished by great labour on the part of the sailors, and by the aid of all the art of navigation, and by the zeal and carefulness of the pilot, and by the favouring influence of the breezes, and the careful observation of the signs of the stars, no one in his sound senses would ascribe the safety of the vessel, when, after being tossed by the waves, and wearied by the billows, it has at last reached the harbour in safety, to anything else than to the mercy of God. Not even the sailors or pilot venture to say, “I have saved the ship,” but they refer all to the mercy of God; not that they feel that they have contributed no skill or labour to save the ship, but because they know that while they contributed the labour, the safety of the vessel was ensured by God. So also in the race of our life we ourselves must expend labour, and bring diligence and zeal to bear; but it is from God that salvation is to be hoped for as the fruit of our labour. Otherwise, if God demand none of our labour, His commandments will appear to be superfluous. In vain, also, does Paul blame some for having fallen from the truth, and praise others for abiding in the faith; and to no purpose does he deliver certain precepts and institutions to the churches: in vain, also, do we ourselves either desire or run after what is good. But it is certain that these things are not done in vain; and it is certain that neither do the apostles give instructions in vain, nor the Lord enact laws without a reason. It follows, therefore, that we declare it to be in vain, rather, for the heretics to speak evil of these good declarations. FROM THE GREEK.
