Abide in me, and I in you. As the branch cannot bear fruit of itself, except it abide in the vine; no more can you, except you abide in me.

We shall know then, by an accurate investigation of the words before us, that the being received of Christ through faith pure and true is the first work of that zeal which is requisite and dear to God. For this is the |385 meaning of being numbered among the branches, which cling to the true Vine, I mean Christ. But the fruit of our second meditation is by no means less in importance than our first, but it has, indeed, an even more pregnant meaning: the loving to be united to God, and to lay fast hold on Him, through a love exhibited in works, which has the fulfilment of the holy and Divine command. For this causes us inseparably to inhere in, and to be closely united to, Him, as the Psalmist expresses it: My soul has been joined unto Thee. The being received then as it were into the rank of branches will not be sufficient for complete joy of heart, or for the sanctification which, as it were, exhibits Christ sanctifying us. But I maintain that the following Him purely through love perfect and unfailing is also necessary. For by this means, the power of union or intimate conjunction with the Father may be best maintained and preserved. When therefore Christ said to His disciples, Already ye are clean because of the word which I have spoken unto you; lest any one of those who have once been purified should be considered incapable of falling away, even though he should bestow no care to remain in a state of grace, He adds this useful injunction----that it is necessary to abide in Him. And what will this be? Nothing else, as I think, but quite obviously that which Paul well expresses: Wherefore let him that thinketh he standeth take heed lest he fall. For a thousand backslidings befall those who think that they are firmly fixed, and who do not take great precautions not to lose the place which they have obtained; and I think that we require the utmost modesty and sobriety, even though a man think himself firmly fixed by the progress he has already made towards establishing himself in righteousness. He then has shown the nature and extent of the punishment of him who has, as it were, been cut off from intimate union with God, through slipping back from negligence into what is wrong, in the statement, As the branch cannot bear fruit of itself, except it abide in the vine, so neither can ye, except ye abide in Me. For unless the branch had supplied to it from its mother the vine the life-producing sap, how would it bear grapes, or what fruit will it bring forth, and from what source? You will perceive that the language of Christ has an application by analogy to ourselves. For no fruit of virtue will spring up anew in us, who have once fallen away from intimate union with Christ. To those, however, who are joined to Him Who is able to strengthen them, and Who nourishes in righteousness, the capacity of bearing fruit will readily be added by the provision and grace of the Spirit, as by life-producing water. And knowing this, the Only-begotten said in the Gospels: If any man thirst, let him come unto Me and drink. And to this, the Evangelist, inspired by the Spirit, has testified, when in his excellent explanation he says: But this spake He of the Spirit, Which they that believe on Him were to receive. And the blessed David, speaking as though to God the Father, thus addressed Him: With Thee is the fountain of life, and Thou shalt give them to drink of the river of blessedness. For by the fountain of Divine and spiritual life and of the fulness of blessedness, who else could be meant but the Son, Who fattens and waters our souls in the position of branches clinging to Him by faith and love, with the quickening and joy-giving grace of the Spirit.
