The Theology of Karl Barth

I just finished reading "Evangelical Theology, an Introduction" by Karl Barth (Eerdmans 1963, reprinted 1996).

Barth appropriately refers to his Trinitarian, Christ-centered Theology as "a theology of freedom" - for this theology speaks of the God of the Gospel - and this Gospel declares God's freedom to grant to us our true freedom in union with Jesus Christ.

This Gospel is the declaration of the history of God's deeds, in Christ, to secure our freedom. In this history, God makes himself known to us. We learn through the deeds of Jesus just who God truly is. There is no God who is not like Jesus Christ. Barth writes:
The God of the Gospel is no lonely God, self-sufficient and self-contained...He is [not] detached from everything that is not himself...he is not imprisoned by his own majesty...He is be the God of man. He exists neither next to man nor merely above him, but rather with him, by him and, most important of all, for him. He is man's God not only as Lord but also as father, brother, friend; and this relationship implies neither a diminution nor in any way a denial, but, instead, a confirmation and display of his divine essence itself (pp. 10-11).
God, in his divine freedom, became one of us and thus one with us, so that we might share in his love and life. This is the Gospel. And this is the basis of our theology, a Theology of Freedom. And we exercise our freedom in Christ, by saying "yes" to God's resounding "YES" said to us already in and through Christ - God for us, with us and in us.
