A good word from Barth
The promise of the Word of God is not as such an empty pledge which always stands, as it were, confronting man. It is the transposing of man into the wholly new state of one who has accepted and appropriated the promise, so that irrespective of his attitude to it he no longer lives without this promise but with it. The claim of the Word of God is not as such a wish or command which remains outside the hearer without impinging on his existence. It is the claiming and commandeering of man. Whatever may be his attitude to God’s claim, man as a hearer of His Word now find himself in the sphere of the divine claim; he is claimed by God. Again, the judgment of the Word of God is not a mere aspect under which man himself remains untouched, just as the same man may seem to be a giant from the standpoint of the ant or a dwarf from the standpoint of the elephant without in fact being any different either way. The judgment of God as such creates not only a new light and therewith a new situation, but also with the new situation a new man who did not exist before but who exists now, being identical with the man who has heard the Word. Again, that would not be the blessing of God’s Word which as benedictio [declared blessed] was not immediately and as such seen and understood to be beneficium [actually blessed] as well, a real placing under God’s good-pleasure and protection.
We find all this expressed in the strongest imaginable way in James 1:18, where (cf. also 1 Peter 1:23) there is reference to the fact that the Christian is begotten of the λογος αληθειας. Then in v. 21 goes on logically to speak of a λογος εμφυτος, i.e., a λογος which, so to speak, belongs to man himself, without which man would no longer be himself.
