The essential of the gospel message by Sir John Newton
I repeat my advice to read the Scriptures with prayer, to keep close the important points, of human depravity, regeneration, the atonement, and the necessity of divine teaching. If a man is born again, hates sin, and depends upon the Savior for life and grace, I care not whether he be an Arminian or a Calvinist. If he be not born again, he is nothing, let him be called by what name he will.
John Newton; Disgrace to Amazing Grace, Crossway Books, 2007.
