3. To consider that this work is, in a peculiar manner, attributed to the Spirit of God; the only moving cause whereof, is his grace. That the Spirit is the author of this work, is not to be proved by experience, as the expressions of divine power therein are, but by scripture; and the scripture is very express as to this matter. Thus, when God promises to _give a new heart; to take away the heart of stone, and to give an heart of flesh, and to cause his people to walk in his statutes_, Ezek. xxxvi. 26, 27. he would _put his Spirit within them_; and elsewhere they are said to have _purified their souls in obeying the truth, through the Spirit_, 1 Pet. i. 22. And our Saviour asserts the necessity of our being _born of the Spirit_, John iii. 5. in order to our entering into the kingdom of God: so that from these, and several other scriptures, that might be referred to, it appears, that effectual calling is the internal powerful work of the Holy Ghost.[25] _Obj. 1._ It is objected, by some, that this doctrine savours of enthusiasm; since it supposes that there is no difference between the Spirit’s internal influences, and inspiration; and to pretend to this, now the miraculous dispensation, which was in the apostle’s days, is ceased, is vain and enthusiastic. _Answ._ To this it may be replied, That the charge of enthusiasm is very unjustly deduced from this doctrine; for we must distinguish between the extraordinary, and the ordinary influence of the Holy Ghost; the former is allowed by all, to be now ceased; and therefore they who pretend to it, are liable to this charge; but it is a very great dishonour cast upon the Holy Ghost to deny his powerful influence or agency in the work of grace; and it renders the condition of the church, at present, in a very material circumstance, so much inferior to what it was of old, that it is incapable of attaining salvation; unless it could be proved that salvation might be attained without the divine energy.
