Christ inviting sinners to come to him for rest

Fifthly, Christ is our sanctification, by being the head of the second Covenant, and so through our mystical union with him, there is a virtue of holiness conveyed from him by being the head of the second Covenant, and we being members of him as the head, we come to have the virtue of holiness to be drawn from him. As it was in Adam, how come we to have so much sin conveyed to us by Adam by propagation, but thus? As we may read in Rom. 5. By one man sin came into the world. Now Adam, he was the head of the first Covenant, and by being the head of that, all mankind are looked upon as members of the first Adam, he being the head in that notion of the Covenant, in that consideration. Adam was not looked upon as a parent only, as the first father, but as the head, and we are not looked upon only as the children of Adam, but as members, so that all men were looked upon as one in Adam, and therefore the Scripture speaks but of two men, the first Adam and the second Adam, that look as sin is conveyed to us, being members of the First Adam, and he being the head of the First Covenant, so grace comes to be conveyed unto the soul by our being members of the second Adam, the Lord Jesus Christ being the head of the second Covenant, here is the way of conveyance of holiness, our union with ⟨p. 310⟩Christ, So that now the holiness that is in Christ, comes to us by virtue of the mystical union. As by virtue of the natural union of the members of the body with the head, there comes animal spirits to the members of the body; so by virtue of our mystical union with Christ our head, there is conveyed holiness and grace to strengthen us against our corruptions. As the ointment did run from Aaron's head […] •to the rest of his members, so Christ that is anoyt• •at hath the oil, not only of gladness but holiness too, doth descend down to all his members by virtue of the union they have with him. And for that end you have a most famous scripture in Rom. 8.2. For the Law of the spirit of life in Christ Jesus, hath made me free from the Law of sin and death. It is a scripture that hath very much in it. What doth he mean by the Law of sin and death? The Law, that is the mighty power that there is in sin, and so in death that comes by sin in the hearts of unbelievers. There is a Law of sin, the strength of sin I speak of, sin hath strength going along with it, hath power with it.
