John 6:43

Therefore He merely says Μὴ γογγύζετε μετʼ ἀλλήλων. That was not the way to light. Nor could He expect to convince all of them, for οὐδεὶς … ἑλκύσῃ αὐτόν, “no one can come to me unless the Father who hath sent me draw him”. ἑλκύειν has the same latitude of meaning as “draw”. It is used of towing a ship, dragging a cart, or pulling on a rope to set sails. But it is also used, John 12:32, of a gentle but powerful moral attraction; “I, if I be lifted up, ἑλκύσω, will draw, etc.” Here, however, it is an inward disposing of the soul to come to Christ, and is the equivalent of the Divine teaching of John 6:45. And what is affirmed is that without this action of God on the individual no one can come to Christ. In order to apprehend the significance of Christ and to give ourselves to Him we must be individually and inwardly aided by God. [Augustine says: “Si trahitur, ait aliquis, invitus venit. Si invitus venit, non credit, si non credit, nec venit. Non enim ad Christum ambulando currimus, sed credendo, nec motu corporis, sed voluntate cordis accedimus. Noli te cogitare invitum trahi: trahitur animus et amore.” And Calvin says: “Quantum ad trahendi modum spectat, non est ille quidem violentus qui hominem cogat externo impulsu, sed tamen efficax est motus Spiritus Sancti, qui homines ex nolentibus et invitis reddit voluntarios”. All that Calvin objects to is that men should be said “proprio motu” to yield themselves to the Divine drawing. cf. a powerful passage from Luther's De libero Arbitrio quoted in Lampe; or as Beza concisely puts it: “Verum quidem est, neminem credere invitum, quum Fides sit assensus. Sed volumus quia datum est nobis ut velimus.”]
