We having the same Spirit of faith,.... By faith here is meant, not the doctrine, but the grace of faith; a believing in the doctrines of the Gospel, and in the person of Christ; an exercise of that grace upon the death and resurrection of Christ; and particularly a looking by faith in full expectation of the saints' resurrection from the dead, and eternal glory, together with a reliance on the power, faithfulness, and promises of God to support under the afflictions of this life.
Now of this faith the Spirit of God is the author; this is not of ourselves, of our own power, it is the free gift of God, and a valuable gift it is; it is of the operation of God, and the produce of his almighty power; and of this the Spirit of God, in conversion, is the powerful operator: hence he is here called the "Spirit of faith".
So the "third" number in the Cabalistic tree of the Jews, the intelligence sanctifying, which answers to the third person in our doctrine of the Trinity, is called ,"Nmwa hnwma and hnwmah ba, "the artificer of faith", and "the author or parent of faith", because from its power faith flows.'
'Which is the "same" in all saints; the Spirit is the same in one as in another, and so is the faith which he is the author of; see 2Pe 1:1. Faith is the same in all the saints that have been from the beginning of the world, under the Old and New Testament dispensations; it was the same in all the churches in the apostle's time, in Rome as at Ephesus, in Ephesus as at Rome, and in Thessalonica as at Rome and Ephesus, and so in all the other churches; though it may be, the apostle may chiefly design the sameness of faith, and of the Spirit, in him and his fellow ministers, and in these Corinthians, though death was working in the one, and life in the other; which appeared in their free and bold ministration of the word, notwithstanding all they met with on account of it, in imitation and encouraged by the example of David,according as it is written, Ps 116:10.
I believed, and therefore have I spoken; we also believe, and therefore speak: where there is true faith, and the true Spirit of faith, there will be a speaking of, for, and in the name of Christ, as there ought to be: for as "with the heart man believeth unto righteousness, so with the mouth confession is made unto salvation".
This is true of believers in common, sooner or later, at one time or another; but more especially of the ministers of the word, who have a firm and well grounded belief in the doctrines of the Gospel, and person of Christ; and therefore speak freely, and without any doubt and hesitation about these things, boldly, and without the fear of men, and sincerely and faithfully, as in the sight of God: hence they make Christ the main subject of their ministry, because they believe in him, and nothing can stop their mouths from speaking of him; faith, and a spirit of faith, fit for public work and service, and give freedom and boldness in the ministration of the Gospel, and are a great support under persecution for the sake of it.
