When we convert and are renewed in the totality of our being, we cross the threshold of our private existence and move out into the open. The inner problems may be most urgent and burning and exciting, but we are not engaged in conversion if we confine ourselves to them.... When we convert and are renewed in the totality of our being, in and with our private responsibility we also accept a public responsibility. For it is the great God of heaven and earth who is for us, and we are for this God. [Church Dogmatics IV: 2, 565]
Barth reminds us that conversion is not primarily about the individual/personal but social/public. Obviously this includes the individual/personal but the end is always the community, the world, the kingdom.
By the way, does anyone know of a free place online where I can read Barth?
