the consistency of Calvinists....by-and-large our answer is always the same....regeneration/illumination occurs before belief (faith). As many other Calvinists have said (in this thread and countless others), God first regenerates the heart of the spiritually dead sinner; without no one can ever come to faith in Jesus Christ.
John Calvin, Commentary on Jn 8:32
"when the Lord regenerates us by his Spirit, he likewise makes us free, so that, loosed from the snares of Satan, we willingly obey righteousness. But regeneration proceeds from faith"
John Calvin, Commentary on Rom 4:16:
"Here, in the first place, the Apostle shows, that nothing is set before faith but mere grace;...Hence, also, we may easily learn, that grace is not to be taken, as some imagine, for the gift of regeneration,"
Belgic Confession:
"We believe that this true faith being wrought in man by the hearing of the Word of God, and the operation of the Holy Ghost, doth regenerate and make him a new man, causing him to live a new life, and freeing him from the bondage of sin."
Reformed Baptist theologian Timothy George, in
Theology of the Reformers:
"being placed into Christ (insitio in Christo) occurs in regeneration which, Calvin was careful to point out, follows from faith as its result"
Prominent late 1700s English Particular Baptist pastor Abraham Booth, in
Glad Tidings to Perishing Sinners:
"To contend, indeed, that regeneration must be prior to faith, and to justification, is like maintaining, That the eldest son of a nobleman must partake of the human nature, before he can have that filial relation to his father, which constitutes him an heir to the paternal estate, and entitles him to those honours which are hereditary in the family. For the human nature, derived from his parents, and the relation of a son, being completely of the same date; there is no such thing as priority, or posteriority, respecting them, either as to the order of time, or the order of nature. They are inseparable; nor can the one exist without the other— Thus it is, I conceive, with regards to regeneration, faith in Christ, and justification before God. For, to consider any man as born of God, but not as a child of God; as a child of God, but not believing in Jesus Christ; as believing in Jesus Christ, but not as justified; or as justified, but not as an heir of immortal felicity; is, either to the last degree absurd, or manifestly contrary to apostolic doctrine."
SBC Founder John Dagg, in his
Manual of Theology:
"Faith is necessary to the Christian character; and must therefore precede regeneration, when this is understood in its widest sense. Even in the restricted sense, in which it denotes the beginning of the spiritual life, faith, in the sense in which James uses the term, may precede."
Charles Spurgeon, in "The Warrant of Faith":
"If I am to preach faith in Christ to a man who is regenerated, then the man, being regenerated, is saved already, and it is an unnecessary and ridiculous thing for me to preach Christ to him, and bid him to believe in order to be saved when he is saved already, being regenerate."
