The Christian Gospel is a matter of decision. It is to be accepted or rejected. All that we who communicate this Gospel can do is to make possible a genuine decision. . . .
True communication of the Gospel means making possible a definite decision for or against it. We who communicate the Gospel must understand the others, we much somehow participate in (their) existence so that their rejection means partly an ejection, a throwing it out in the moment in which it starts to take root in them. To this point we can bring them, and that is what communicating the Gospel means.
