It is written in the prophets, And they shall be all taught of God. Every man therefore that has heard, and has learned of the Father, comes unto me.

It is written, &c. He quotes Isaiah 54:13, "All thy children shall be taught of the Lord." Jeremiah ( Jeremiah 31:33) has a similar prophecy, and Joel ( Joel 2:28). Because what Christ said seemed strange to the Jews, No one can come to Me, except My Father draw him, Christ confirms it out of Isaiah and the Prophets, who assert that all the children or disciples of Christ would be taught of God. But to be taught by God is to be drawn by God, for this is the force of the Hebrew limmude.
Now, they will be taught by God in that He will at the external voice of Christ and His disciples teach their minds inwardly, illuminate and inspire them, to believe in and obey Him. Whereas previously in the ancient Law, God taught the people exteriorly rather than interiorly, by prophets, priests, and by the Holy Scriptures. Wherefore "where God is the Teacher," says S. Leo, "there are the lessons quickly learned." Hear S. Augustine (in Epist1 S. Jo. Tract3) "The sound of our words strikes the ear, the Master is within. I have spoken to all, but to whomsoever that unction speaketh not inwardly, whom the Holy Ghost teacheth not within, such depart untaught. The outward instructions and admonitions are some sort of aid; but it is He who sitteth in heaven who teaches the heart. Wherefore He saith Himself in the Gospel, "Call no one your master upon earth, for one is your Master, Christ." He indeed speaks to you inwardly when no mortal man is by. Where His inspiration, His unction is not, outward words are an empty breath."
Every one who hath heard . . . and learned, the Arabic adds, and knoweth. See how He explains the drawing of the Father. He is drawn by the Father who is inwardly taught by Him, i.e, whose understanding is illuminated by the Father, and his will inflamed, that he may believe in and follow Me. And he hath learned, or he does learn, that Isaiah , he receives My illumination in his intellect, and My impulse in his will: and he acquiesces, and freely consents. This man comes to Me, i.e, he believes in Me as the Messiah, and obeys Me. For the two feet, not of the body, but of the soul, by which she comes to Christ, are the understanding enlightened by God, and the will impelled and inflamed by Him. Hence S. Augustine (de Predest. Sanc. c8) says, "If every one who hath heard and learned of the Father cometh, assuredly every one who cometh not, hath not heard, nor learned of the Father. For if he had heard and learned, he would come." He subjoins, "This school is far remote from fleshly sense, in which the Father is heard, and teaches us to come to the Son. There, too, is the Son Himself, because He is His Word, by whom He thus teaches us: and this He does not through the ears of the flesh, but of the heart. There also at the same time, is the Spirit of the Father and the Son. And He neither refrains from teaching, nor does He teach differently. For we have learned that the works of the Trinity are inseparable." And after an interval, "Why therefore does He not teach all to come to Christ, unless because all whom He teaches, He teaches in mercy? But whom He teacheth not, in judgment He teacheth them not. For He hath mercy upon whom He will, and whom He wills He hardeneth. But He is merciful, and doeth good, and when He hardeneth He requiteth justly. This grace therefore which is secretly given to human hearts by the Divine bounty, is rejected by no hard heart. For this reason is it given that the hardness of the heart may be first taken away. When therefore the Father is heard and teaches inwardly that we should come to the Song of Solomon , He takes away the heart of stone, and gives a heart of flesh, as He promised by His prophet. For so He makes the sons of promise vessels of mercy which He has prepared for glory."
