"The Christian is the man who no longer seeks his salvation, his deliverance, his justification in himself, but in Jesus Christ alone. He knows that God’s Word in Jesus Christ pronounces him guilty, even when he does not feel his guilt, and God’s Word in Jesus Christ pronounces him not guilty and righteous, even when he does not feel righteous at all. The Christian no longer lives of himself, by his own claims and his own justification, but by God’s claims and God’s justification. He lives wholly by God’s Word pronounced upon him."
Dietrich Bonhoeffer from Life together
