Walter Marshall

The way to get holy endowments and qualifications necessary to frame and enable us for the immediate practice of the law, is to receive them out of the fullness of Christ, by fellowship with Him; and that we may have this fellowship, we must be in Christ, and have Christ Himself in us, by a mystical union with Him.

And, as our natural corruption was produced originally in the first Adam, and propagated from him to us, so our new nature and holiness is first produced in Christ, and derived from Him to us, or as it were propagated. So that we are not at all to work together with Christ, in making or producing that holy frame in us, but only to take it to ourselves, and use it in our holy practice, as made ready to our hands.

The end of Christ's incarnation, death and resurrection was to prepare and form a holy nature and frame for us in Himself, to be communicated to us by union and fellowship with Him; and not to enable us to produce in ourselves the first original of such a holy nature by our own endeavours.
