Faith is never identical with piety.
More Karl Barth quotes :
Religion is the possibility of the removal of every ground of confidence except confidence in God alone.Karl Barth
Man can certainly flee from God... but he cannot escape him. He can certainly hate God and be hateful to God, but he cannot change into its opposite the eternal love of God which triumphs even in his hate.Karl Barth
Faith in God's revelation has nothing to do with an ideology which glorifies the status quo.Karl Barth
