Starting with an analysis of the close relation of Trinity and revelation in Barth, J'ngel goes on to look at Barth's action of divine objectivity in relation to human subjectivity. He closes with a discussion of the ontological implications of God's self-manifestation at the Cross. This translation of J'ngel's Gottes Sein ist in Werden also incorporates material from the 1975 German edition, together with a substantial new introduction by Professor John Webster.
