John Witherspoon (1723-1794) was a key Presbyterian minister during the Revolutionary War period in American history, and is regarded among the Founding Fathers. As the only active clergy to sign the Declaration of Independence, to sign the Articles of Confederation, approve the Constitution, and serve as Moderator of the General Assembly for American Presbyterians, Witherspoon established himself in sacred and secular history of this nation. He has an important treatise on the doctrine of being born again, or regeneration.
Witherspoon wrote movingly about preaching the Gospel to different socio-economic groups, especially the poor. Here is a longer passage, where after addressing the unique situation the Scriptures give to those suffering in poverty, he says:
But does not the Savior of sinners beseech you to be reconciled unto God? He entreats you to come unto Him that you may have life. He regardeth not the persons of men, but values a precious immortal spirit as much in a mean cottage as in a splendid palace. Your rags and nakedness can be no hindrance to your obtaining His favor. He counsels you “to buy of Him gold tried in the fire, that you may be rich, and white rainment that you may be clothed.”
