<p>2:11- see on Heb. 11:26.</p><p><i>For both he that sanctifies and they that are sanctified are all of the same nature- </i>This is yet more evidence that the Lord was not an Angel. He had the nature of those whom He sanctified in order to achieve that sanctification. This inspired principle is profound and underpins the representative nature of the Lord's work and sacrifice. The sanctifier must be of the same nature as the sanctified. This raises a serious question about the validity of the Mosaic sacrifices; they were only acceptable by reason of the truly representative Messianic sacrifice to which they pointed forward. And as Paul will later point out, it was therefore not possible for the blood of animals to take away human sin; the sanctification had to be achieved by a sanctifier of the same nature. But &quot;of the same nature&quot; is literally &quot;out of one&quot;. The argument could equally be that they were of the same Father, which is why He is not ashamed to call us brothers, for we are of the same one Father. In this case, Paul read the virgin birth as no fundamental barrier to the Lord's identification with us, for we and Jesus are all &quot;of the same one&quot;, i.e. God.</p><p><i>For this cause he is not ashamed to call them brothers</i>- The very fact Christ calls us His brothers (as in Mt. 12:50) is seen as proof of Christ's humanity, that it was men and not Angels who were His brothers. The Lord shall be ashamed of His association with some at the last day, and of us He will not be ashamed in that day (s.w. Mk. 8:38). But His unashamed association with us begins now in this life. Because God's Son is unashamed now of having us as His brothers, therefore the Father is not ashamed to be known as our God (11:16 s.w.).</p>
