Newton On Calvinistic Proselytizing

If I thought a certain person feared sin, loved the Word of God, and was seeking after Jesus, I would not walk the length of my study to proselyte him to the Calvinistic doctrines. Not because I think them mere opinions, or of little importance to a believer—I think the contrary; but because I believe these doctrines will do no one any good until he is taught them of God. I believe a too hasty assent to Calvinistic principles, before a person is duly acquainted with the plague of his own heart, is one principal cause of that lightness of profession which so lamentably abounds in this day, a chief reason why many professors are rash, heady, high-minded, contentious about words, and sadly remiss as to the divine means of grace.
