Spurgeon et al believed what (almost?) all Calvinists believe: that the Gospel must be preached to all, in the hope and expectation that God will open the hearts of His people to receive the words spoken to them (Acts 13:48; 16:14).Particular Baptists of yesteryear who warned against these 'regeneration before faith' & 'born again before faith' & etc. contrivances:
Charles Spurgeon, "The Warrant of Faith"
"If I am to preach faith in Christ to a man who is regenerated, then the man, being regenerated, is already saved! It is unnecessary and ridiculous for me to preach Christ to him, and bid him to believe in order to be saved, when he is saved already, being regenerate!"
Abraham Booth, "Glad Tidings to Perishing Sinners":
"the page of inspiration does not warrant our supposing, that any one is born of God, before he believes in Jesus Christ....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."
The 1689 London Baptist Assembly
"none can be said to be actually reconciled, justified, or adopted, until they are really implanted into Jesus Christ by faith; and so by virtue of this their union with him, have these fundamental benefits actually conveyed unto them. And this, we conceive, is fully evidenced, because the scripture attributes all these benefits to faith as the instrumental cause of them, Rom. iii. 25. v. 1, 11. Gal. iii. 26. And gives such representation of the state of the elect before faith, as is altogether inconsistent with an actual right in them. Eph. ii. 1, 2, 3, 12."
The idea that the Gospel should be preached only to the elect is plainly crackers, but no more so that hoping that those dead in trespasses will somehow make themselves alive.
