Not that any man hath seen the Father, save he which is of God, he hath seen the Father. Not that any man hath seen the Father - He does not teach men by appearing personally before them, or by any other outward voice than that of his word and messengers; but he teaches by his Spirit. This teaching from God implies:
1. That they shall have proper instruction.
2. That they shall comprehend it; for, when God teaches, there is no delay in learning. And,
3. That this teaching should be by the influence of the Holy Ghost upon their minds.
He which is of God - That is, Christ alone: neither Moses nor any of the prophets had ever seen God: Jesus, who lay in the bosom of the Father, He saw and revealed him, John 1:18.
