FAITH OF LIVING CHRISTIANS

I am crucified with Christ,.... Not literally, for so only the two thieves were crucified with him, but mystically; Christ was crucified for him in his room and stead, and so he was crucified with him, and in him, as his head and representative. Christ sustained the persons of all his people, and what he did and suffered was in their name, and on their account, and so they were crucified and suffered with him, as they are said to be buried with him, and to be risen with him, and to sit together in heavenly places in him. Moreover, their old man was crucified with him; when he was crucified, all their sins, the whole body of them, were laid upon him, and he bore them, and bore them away, destroyed and made an end of them; they received their mortal wound by his crucifixion and death, so as never to be able to have any damning power over them; and in consequence of this the affections and lusts are crucified, and the deeds of the body of sin mortified by the Spirit and grace of God, in regeneration and sanctification, so as not to have the dominion over them; the world is crucified to them, and they to the world; and this is another reason proving that justification by Christ is no licentious doctrine. This clause is, in the Vulgate Latin, Syriac, Arabic, and Ethiopic versions, put at the end of the preceding verse.
Nevertheless I live; which is to be understood, not of his natural, but of his spiritual life; the life of justification he lived, by faith, on the righteousness of Christ; and the life of sanctification which he had from Christ, by the quickening influences of his Spirit, by virtue of which he walked in newness of life. The believer is a mere paradox, he is dead to the law, and "yet lives" to God; he is crucified with Christ, and yet lives by him; yea, a crucified Christ lives in him.
Yet not I; not the same I as before, but quite another man, a new creature: he did not now live as in his state of unregeneracy, and whilst in Judaism; he was not now Saul the blasphemer, the persecutor, and injurious person; nor did he now live Saul the Pharisee: or the life he had was not of his own obtaining and procuring; his life of righteousness was not of himself, but Christ; his being quickened, or having principles of life and holiness implanted in him, was not by himself, but by the Spirit; and the holy life and conversation he lived was not owing to himself, to his power and strength, but to the grace of God; or it was not properly himself, or so much he that lived,
but Christ liveth in me: who was not only the author and maintainer of his spiritual life, but the life itself; he was formed in his soul, dwelt in his heart, was united to him, was one with him, whence all vital principles and vital actions sprung, and all the communion and comforts of a spiritual life flowed.
And the life which I now live in the flesh; in the body, whilst in this mortal state, whereby he distinguishes that spiritual life he had from Christ, and through Christ's living in him, both from the natural life of his body, and from that eternal life he expected to live in another world; and which, he says,
I live by the faith of the Son of God; meaning, not that faith which Christ, as man, had, but that of which he is the author and object, by which the just man lives; not upon it, for the believer does not live upon any of his graces, no, not upon faith, but by faith on Christ, the object; looking to him for pardon, righteousness, peace, joy, comfort, every supply of grace, and eternal salvation: which object is described as "the Son of God"; who is truly God, equal with his Father; so that he did not live upon a creature, or forsake the fountain of living waters, but upon the only begotten Son of God, who is full of grace and truth: of whom he further says,
who loved me; before the foundation of the world, from everlasting, prior to his love to him; and freely, without any regard to worth or merit, and though he was a blasphemer and a persecutor; and him personally, and particularly, in a distinguishing manner, of which he had a special knowledge and application by the Spirit of God; and was a reason and argument constraining him, and prevailing on him to live to him who loved him, and died for him, or, as he adds,
and gave himself for me; his whole self, his soul and body, as in union with his divine person, into the hands of justice, and unto death, in his room and stead, as an offering and sacrifice for sin, and which he did freely and voluntarily; and is a strong and full proof of his love to him. Now though Christ gave his life a ransom for many, and himself for his whole church, and all the members of his mystical body, yet the apostle speaks of this matter as singularly respecting himself, as if almost he was the only person Christ loved and died for; which shows that faith deals with Christ not in a general way, as the Saviour of the world, but with a special regard to a man's self: this is the life of faith; and these considerations of the person, love, and grace of Christ, animate and encourage faith in its exercises on him.
