Testifying both to the Jews, and also to the Greeks,.... To the Jews first in their synagogue, and then to both Jews and Greeks, or Gentiles, in the school of Tyrannus; opening and explaining to both the nature and use, urging and insisting upon, and proving by undeniable testimonies the necessity,of repentance toward God and faith toward our Lord Jesus Christ: the former of these is not a legal repentance, but an evangelical one; which flows from a sense of the love of God, and an application of pardoning grace and mercy, and is always attended with hope, at least of interest in it, and as here with faith in Christ Jesus: it lies in a true sight and sense of sin, as exceeding sinful, being contrary to the nature and law of God, and a deformation of the image of God in man, as well as followed with dreadful and pernicious consequences; and in a godly sorrow for it, as it is committed against a God of infinite purity and holiness, and of love, grace, and mercy; and it shows itself in shame for sin, and blushing at it, and in an ingenious confession of it, and forsaking it: and the latter of these is not an historical faith, or an assent of the mind to whatsoever is true concerning the person, office, and grace of Christ; but is a spiritual act of the soul upon him; it is a looking and going out to him, a laying hold and leaning on him, and trusting in him, for grace, righteousness, peace, pardon, life, and salvation.
Now these two were the sum of the apostle's ministry; this is a breviary or compendium of it; a form of sound words held fast and published by him: and as these two go together as doctrines in the ministry of the word, they go together as graces in the experience of the saints; where the one is, there the other is; they are wrought in the soul at one and the same time, by one and the same hand; the one is not before the other in order of time, however it may be in order of working, or as to visible observation; repentance is mentioned before faith, not that it precedes it, though it may be discerned in its outward acts before it; yet faith as to its inward exercise on Christ is full as early, if not earlier; souls first look to Christ by faith, and then they mourn in tears of evangelical repentance, Zec 12:10 though the order of the Gospel ministry is very fitly here expressed, which is first to lay before sinners the evil of sin, and their danger by it, in order to convince of it, and bring to repentance for it; and then to direct and encourage them to faith in Christ Jesus, as in the case of the jailer, Ac 16:29 and this is, generally speaking, the order and method in which the Holy Spirit proceeds; he is first a spirit of conviction and illumination, he shows to souls the exceeding sinfulness of sin, causes them to loath it and themselves for it, and humbles them under a sense of it; and then he is a spirit of faith, he reveals Christ unto them as God's way or salvation, and works faith in them to believe in him.
