Are all of one.--Of one Father. This is the connecting link between Hebrews 2:11 and Hebrews 2:10, which speaks of the "many sons" and their Saviour. Though His sonship is unique and infinitely exalted, He is not ashamed to own them as brethren.
and they who are sanctified; the sons brought to glory; they are not naturally holy, nor so of themselves, they are made holy; all that are sons are made holy; whom God adopts into his family, he regenerates: sanctification is absolutely necessary to their being brought to glory; and between the sanctifier and the sanctified there is a likeness, as there ought to be: they are
all of one: they are both of one God and Father, Christ's God is their God, and his Father is their Father; they are of one body, Christ is the head, and they are members; they are of one covenant, Christ is the surety, Mediator, and messenger of it, and they share in all its blessings and promises; they are of one man, Adam, Christ is a Son of Adam, though not by ordinary generation, they descend from him in the common way; they are all of one nature, of one blood; Christ has took part of the same flesh and blood with them:
for which cause he is not ashamed to call them brethren; Christ, and these sons that are sanctified, stand in the relation of brethren to each other; Christ is the firstborn among many brethren; he is a brother born for the day of adversity, and one that sticks closer than a brother: and this relation is founded both upon the incarnation of Christ, who thereby became his people's "Goel"; or near kinsman, yea, brother, Sol 8:1 and upon their adoption unto his Father's family, which is made manifest by their regeneration, and by their doing his Father's will under the influence of his grace and Spirit, Matthew 12:49 and this relation Christ owns; he called his disciples brethren, when God had raised him from the dead, and given him glory; and so he will call all his saints, even the meanest of them, in the great day, Matthew 28:10, and "he is not ashamed" to do it; he does not disdain it, though he is God over all, and the Son of God, and is also in his human nature made higher than the heavens; which shows the wonderful condescension of Christ, and the honour that is put upon the saints; and may teach them not to despise the meanest among them: such a relation the Jews own will be between the Messiah and the Israelites. The Targumist on Sol 8:1 paraphrases the words thus;
"when the King Messiah shall be revealed to the congregation of Israel, the children of Israel shall say unto him, Come, be thou with us, for "a brother", or "be thou our brother".''
Nor can they say this will reflect any discredit upon Christ, when they make such a relation to be between God and them. The Israelites, they say (f), are called, "the brethren of the holy blessed God"; in proof of which they often produce Psalm 122:8 as being the words of God to them; and again, interpreting those words in Leviticus 25:48 "one of his brethren may redeem him", this, say (g) they, is the holy blessed God.
