It is written in the prophets, And they shall be all taught of God. Every man therefore that hath heard, and hath learned of the Father, cometh unto me.
It is written in the Prophets (in Isaiah 54:13; Jeremiah 31:33-34) Other similar passages may also have been in view. Our Lord thus falls back upon Scripture authority for this seemingly hard saying.
And they shall be all taught of God - not by external revelation merely, but by internal illumination, corresponding to true "drawing" of John 6:44.
Every man therefore that hath heard, and hath learned of the Father (who hath been thus efficaciously taught of Him), cometh unto me - with absolute certainty, yet in every case voluntarily, as above explained:
q. d., 'As none can come to Me except as divinely drawn, so none thus drawn shall fail to come.'
