Any one who speaks of God as though He were a cousin, about whom, naturally, one knows everything, really knows nothing at all of God. The first and most important fact that we can know about God is ever this: we know nothing of Him, except what He himself has revealed to us.
Emil Brunner, Our Faith, Translated by John Rilling, (New York: Scribner’s Sons, 1954), 11.


By convincing man of his sin and weakness, it forced him to seek a remedy in Christ by faith (as we have already said). Again, these two conditions are proposed because they are necessary to the salvation for the sinner: perfect obedience in Christ to fulfill the righteousness of the law, without which the justice of God did not permit life to be given to us; faith however in us that the perfect obedience and satisfaction of Christ might be applied to us and become ours by imputation. Thus what was demanded of us in the covenant of works is fulfilled by Christ in the covenant of grace. Nor is it absurd that in this way justification takes place by works and by faith – by works of Christ and by our faith. And thus in sweet harmony the law and the gospel meet together in this covenant. The law is not administered without the gospel, nor the gospel without the law. So that it is as it were a legal-gospel and an evangelical-law; a gospel full of obedience and a law full of faith. So the gospel does not destroy the law, but establishes it (Rom 3:31) by giving us Christ, who perfectly fulfilled it. And the law is not against the gospel, since it refers and leads us to it as its end.
