Matthew Poole and continuators on John 2:23

23 ¶ Now when he was at Jerusalem at the passover, in the feast day, many believed in his Name , when they saw the miracles which he did .

To believe in Christs name, and to believe in Christ himself, are one and the same thing; as it is the same to call upon God, and to call upon the Name of God: so Acts 3.16. The meaning is, that they believed the things which were published concerning his Person and Office, yet the Periphrasis, Believing in his name, is not vain; but declareth a mutual relation betwixt God and the Word, by the Preaching of which he maketh himself known to the World. True faith cometh by hearing, and hearing by the Word of God. I think it is to no purpose disputed here by some, Whether the Faith here mentioned was true Faith, yea or no. It appeareth by what followeth, that it was not true justifying Faith; but it was true in its kind. To make up true justifying saving Faith, which the Apostle calls the Faith of Gods elect, three things are required, 1. A knowledg of the Proposition of the Word revealing Christ; this is acquired by Reading, Hearing, Meditation, &c. 2. The second i[illegible: 1 letter] Assent, which is the act of the understanding, agreeing in the truth of the word revealed, when such an Assent is given to a Proposition, if merely upon the Divine Revelation of it; this is Faith, a true Faith in its kind. 3. Upon this now (in those who savingly believe), the Will closeth with Christ as an adequate object; for it receiveth him, accepteth him, relies on him as its Saviour, and moveth by the Affections, to Love, Desire, Hope, Rejoyce in him; and commandeth the outward man into an Obedience to his Law. Now it is very possible, that through a common Influence of the Holy Spirit of God, men upon the hearing of the Word; especially, having the advantage of seeing miraculous Operations confirming the Word, may give a true Assent to the Proposition of the Word, as a Proposition of Truth, and yet may never receive Christ as their Saviour, close with him, trust in him, desire, love, or obey him; this was the case of these Persons (many at least of them.)

They believed, seeing the miracles which Christ did; they wanted a due knowledg of Christ founded in the Word; neither had they any certain, steady, fixed Assent, founded in the discerning the Truth of the Proposition; their Assent was sudden, founded onely upon the Miracles they saw wrought, so as tho they might have some confidence in him, as a famous Person, and some great Prince, from whom they might expect some earthly good; yet this was all, which was far enough from true saving Faith.
