“The Word of Christ is for us the word of decision, which, so far as we believe, gives us salvation, and, precisely because it summons us to this decision, forbids us to believe in a deliverance which awaits us, or anyone else outside the sphere of faith. Just as we ought to know that God alone in Jesus Christ is the God of Grace, and outside of Jesus Christ the God of Wrath, so ought we to know that He is only gracious to him who believes, but that He is not so to him who is outside the sphere of faith.
But this cannot be for us an object of theoretical doctrine or even of imaginary ideas. This is said in order that we may believe, and it is for each of us to tell others as we have heard it, in order that they, too, may come to believe.
This is our business, but nothing else. We must absolutely resist the inclination to draw “logical conclusions”, since they only lead to one of two errors : either to the doctrine of the double decree or to the doctrine of universal salvation, each of which removes the reality of the decision of faith. Only the renunciation of the logically satisfying theory creates room for true decision; but the Gospel is the Word which confronts us with the summons to decision.” — Emil Brunner (emphasis mine)
