Puritan Minister Cotton Mather (1663-1728) said in one of his writings, “What Must I Do To Be Saved?” of the Gospel:
And what Better, what other Answer can be given, (Other Foundation can no man Lay!) to this Question, but what the Apostles of God gave to it of old? When the poor man said what must I do to be Saved, we read they said Believe on the Lord Jesus Christ, and thou shalt be saved.
This is the Sum of the Gospel; This is the Charge given to the Ministers of the Gospel; Mark 16:15, 16 "Preach the Gospel to every Creature. He that believeth… shall be saved."
Faith in the Lord Jesus Christ, who is the Only Saviour; This, This must be found in all that will be saved.
The faith, which is, A satisfaction of the mind in the way of Salvation by a Glorious Christ Revealed in the Gospel.
The Faith by which we deny our selves, and Rely on a Glorious Christ, for all Salvation.
The Faith by which we Receive a Glorious Christ, and Rest on Him for Salvation as He is offered unto us.
But How must this faith operate in all that would be saved?
Oh Set! Your Hearts to these things; they are not vain things; Your Lives, the very Lives of your Souls are concerned in them.
If your Hearts may now fall in with these things, and form’d and shap’d according to the Evangelical Mold of them lo, This Day Salvation is come unto your souls. Glorious Lord, incline the hearts of our People, to do what must be done that so thy Salvation may be bestow’d upon them.
