But I said unto you, That ye also have seen me, and believe not.

People's New Testament

6:36 Ye also have seen me, and believe not. They had asked a work in order that they might believe, which was a confession of their unbelief. They ask for the bread of life, but they can only partake of it by believing in him. He therefore points out the one obstacle to obtaining what they had asked for.

Wesley's Notes

6:36 I have told you - Namely, John 6:26.

Jamieson-Fausset-Brown Bible Commentary

36. But . ye have seen me, and believe not-seen Him not in His mere bodily presence, but in all the majesty of His life, His teaching, His works.

Matthew Henry's Concise Commentary

6:36-46 The discovery of their guilt, danger, and remedy, by the teaching of the Holy Spirit, makes men willing and glad to come, and to give up every thing which hinders applying to him for salvation. The Father's will is, that not one of those who were given to the Son, should be rejected or lost by him. No one will come, till Divine grace has subdued, and in part changed his heart; therefore no one who comes will ever be cast out. The gospel finds none willing to be saved in the humbling, holy manner, made known therein; but God draws with his word and the Holy Ghost; and man's duty is to hear and learn; that is to say, to receive the grace offered, and consent to the promise. None had seen the Father but his beloved Son; and the Jews must expect to be taught by his inward power upon their minds, and by his word, and the ministers whom he sent among them.
