God’s Being is in Becoming [PDF ebook] 
The Trinitarian Being of God in the Theology of Karl Barth

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.
