Faith is created by God in connection with the revelation of the gospel within the heart of the elect, which is the "substance" as well as the "hope" of justifying faith - Mt. 16:16-17; 2 Cor. 4:6; Gal. 1:15-16.
A. 2 Cor. 4:6 clearly and explicitly gives the creation of literal light by the effectual spoken word of God in Genesis 1:3 to be analgous with the creation of the metaphorical light of knowledge of God in the person of Christ in the heart by the effectual empowering of the gospel by God.
1. The Clear reference to Genesis 1:3 is indisputable - " For God, who commanded the light to shine out of darkness,"
2. That it is provided as an analogous manner is indisputable - "hath shined in our hearts, to give the light of the knowledge of the glory of God in the face of Jesus Christ."
3. In Genesis 1:3 light was created by God speaking it into existence - this is indisputable.
4. In 2 Cor. 4:6 the direct analogy is God creating the metaphorical light of knowledge by speaking it into existence IN THE HEART (as no human can work in the heart).
5. The Word empowered by God in the heart to reveal this light of knowledge is the gospel and it is not the work of any human preacher as Paul immediately denies this work in the heart is of human power but is the power of God - 7 But we have this treasure in earthen vessels, that the excellency of the power may be of God, and not of us.
6. The power he is speaking of is the power that creates the light of knowledge within the human heart in the previous verse.
7. In 2 Cor. 4:4-6 the only possible application of verse 6 is the gospel knowledge of Christ and this is implanted in the heart by a creative act of God.
8. Faith has no existence apart from "substance" and it is that same "substance" which is the basis of "hope" (Heb. 11:4). Who can deny that in the context of 2 Cor. 4:4-6 that the knowledge revealed by God in the heart is the gospel of Christ as the gospel is the subject matter in the previous three verses? This is an explicit statement by Paul that the very substance and hope of justifying faith is the creative work of God in the human heart (v. 6) and not of man (v. 7).
B. Matthew 16:16-17 and Gal. 1:15-16 clearly demands that the profession of faith in Christ is not something originating with Peter or Paul or any human but has its sole origin by revelation from God just as Paul teaches in 2 Cor. 4:6:
Mt. 16:16 And Simon Peter answered and said, Thou art the Christ, the Son of the living God.
17 And Jesus answered and said unto him, Blessed art thou, Simon Barjona: for flesh and blood hath not revealed it unto thee, but my Father which is in heaven.
Gal. 1:11 But I certify you, brethren, that the gospel which was preached of me is not after man.
12 For I neither received it of man, neither was I taught it, but by the revelation of Jesus Christ........
15 But when it pleased God, who separated me from my mother’s womb, and called me by his grace,
16 To reveal his Son in me,
1. In both cases it is the Son that is revealed by the Father to Peter and Paul ("my father....reveal HIS Son in me")
2. In both cases it is by REVELATION ("revealed it unto thee....my Father.......by the revelation....reveal his son in me")
3. In both cases it does not have its origin with other humans/preachers ("for flesh and blood hath not revealed it..........not after man. ..neither received of man, neither was I taught it.").
4. God called Paul from His mother's womb as effectually as he called him by new birth ("when it pleased God, who separated me from my mother's womb, AND called my by his grace to reveal his son in me"
5. Therefore, the substance of a true confession of faith is not of man but it is the work of God by divine revelation.
C. John 6:44 denies that faith originates with man - "no man CAN come to me"
1. Jesus does not say "some men" can - but "no man can"
2. In context "come to me" is defined previously in John 6:35 as believing in him for eternal life. It is metaphorically described as "eating" and "drinking" of Christ as one would partake of food, faith is partaking of Christ.
3. Coming to Christ by faith for eternal life IS NOT OF MAN but of God - clearly stated. This is clearly stated in John 6:29 "this is the WORK OF GOD that ye believe." This is then proven in John 6:37-39 as the work of God that precedes "ALL" who come to Christ by faith is having been given by God before the incarnation. This is additionally proven by the fact that he work of God called drawing must precede any man coming to Christ by faith in John 6:44. This is again proven negatively in John 6:64-65 where the cause for those who never truly believed in their heart "from the beginning" of their profession is that "it" (ability to come) was never given unto them by the Father.
D. Paul tells the Philippians that the ability to believe in Christ was "given" unto them - Philip. 1:29
29 For unto you it is given in the behalf of Christ, not only to believe on him, but also to suffer for his sake;
1. The immediate preceding verses are about the gospel and response to tribulation (vv. 27-28) which is the precise order in verse 29 (believe on him....also to suffer" for him).
2. God's will is the source of circumstantial sufferings as much as His will is the source of saving faith as a creative act (Mt. 16:17; Gal. 1:16; 2 Cor. 4:6; Jn. 6:44; 64-65).
CONCLUSION: In all three of the first texts (2 Cor. 4:6; Mt. 16:16-17; Gal. 1:15-16) the very substance of saving faith, that the mouth confesses (Mt. 16:16) does not originate from man but originates as a creative act of God or as a divine revelation in the heart. In all three texts this divine revelation as a creative act of God precedes any true confession of faith and is explicitly stated to be the true origin and source of such a confession. John 6:44 denies that saving faith has its origin with man but explicitly demands its origin is with the work of God. Hence, saving faith is instilled in man by the work of God as the only other alternative is it is of man and John 6:44 denies that. Philippians 1:29 clearly and explicitly states that saving faith in the gospel of Christ is given by God and is as much under the control of God's will as the circumstances (providence) that result in the privilege for suffering for Christ.
