Such was the love of the Son of God to the human nature, that he desired a most near and close union with it, something like the union in the persons of the Trinity, nearer than there can be between any two distinct [beings]. This moved him to make the human become one with him, and himself to be one of mankind that should represent all the rest, for Christ calls us brethren and is one of us.
How should [we] be encouraged, when we have such a Mediator! 'Tis one of us that is to plead for us, one that God from love to us has received into his own person from among us.
And 'tis so congruous that it should be so, and is also so agreeable to the Scripture, that it much confirms in me the truth of the Christian religion. (Jonathan Edwards, Miscellanies #183, paragraphing added)
