"No one can come to me unless the Father who sent me draws him". E.S.V.
The verb ἑλκύσῃ (helkysē) [from the root ἑλκω (helkó)] is translated "draws". Does drawing something guarantee a positive result, i.e. that the drawn thing actually moves?
In John 21:6 they intended to helkysai the net but it would not move. Or, suppose a rope is put round the neck of a stubborn mule, and the Jews have just been described [John 6:43] as people who grumble, [complain rather than comply],then here too pulling/drawing may produce no positive effect. The thing drawn does not necessarily move.
At this point we could broaden out to consider under what conditions of grace drawing might produce a positive result. But again, does helkyse imply anything more than a pull or intention which may or may not produce something? Acts 16:19 shows us that heilkysan can be an act of force, but that by itself does not prove that it always is. In common parlance we can feel drawn to do various things [eat something not good for us] which we do not end up doing. How should we see "draw"?
