<p>6:46 <i>Not that anyone has seen the Father, save he that is from God, he has seen the Father</i>- The Lord adds this as a foil or caveat to His teaching in :45 that the one who has learned of God comes to His Son. He means to say that total knowledge of Him is not possible, just as Moses could not 'see' the Father, neither can anyone claim to have fully 'seen' or perceived Him, except the Son. The point is to guard against the Jewish idea of justification by knowledge, as if 'learning' of the Father meant totally 'seeing' him. Such total, perfect knowledge is not necessary nor even attainable; what is of the essence is to allow ourselves to be drawn by the Father towards His Son.</p><p>The fact the Lord <i>had </i>seen God, as the One &quot;from God&quot;, contrasts powerfully with how Moses could <i>not</i> see Him.</p>
