Church was always founded in the person of Christ. The primary adoption
of the chosen people depended on the grace of the Mediator, and Christ
was always held forth to the holy fathers under the law as the object of
their faith.

It deeply concerns us that He who was to become our Mediator should be
very God and very man. The work to be by Him performed was of no common
description, being to restore us to the divine favour so as to make us
sons of God and heirs of the heavenly kingdom. In Him the divinity was
so conjoined with the humanity that the entire properties of each nature
remained entire, and yet the two natures constitute only one Christ.
Everything needful for us exists in Christ.

When we see that the whole sum of our salvation, and every single part
of it, are comprehended in Christ, we must beware of deriving even the
minutest part of it from any other quarter. If we seek salvation, we are
taught by the very name of Jesus that He possesses it; if we seek any
other gifts of the Spirit, we shall find them in His unction; strength
in His permanent government; purity in His conception; indulgence in His
nativity, in which He was made like us in all respects, in order that He
might learn to sympathise with us; if we seek redemption we shall find
it in His passion; acquittal in His condemnation; remission of the curse
in His cross; satisfaction in His sacrifice; purification in His blood;
reconciliation in His descent into hell; mortification of the flesh in
His sepulchre; newness of life in His resurrection; immortality also in
His resurrection; the inheritance of a celestial kingdom in His entrance
into heaven; protection, security, and the abundant supply of all
blessings, in His kingdom; secure anticipation of judgment in the power
of judging committed to Him. In fine, since in Him blessings are
treasured up, let us draw a full supply from Him, and none from another
