“Jesus Christ is not only a Savior of few, but He offers Himself to all. As often as the gospel is preached to us, we ought to consider that God calls us to Him; and if we attend to this call, it shall not be in vain, neither shall it be lost labor. But can we come to Him without any assistance, except what we derive from our own nature? Alas, we cannot!”

John Calvin, The Mystery of Godliness and Other Sermons [Soli Deo Gloria], p. 109 (on 1 Tim. 2:3-5 ).
