Barth’s Christocentricism is worthwhile and helps overcome is slightly odd view of sin at times.
“In view of Christ’s Cross we are invited on the one hand to realize the magnitude and weight of our sin in what our forgiveness cost. In the strict sense there is not knowledge of sin except in light of Christ’s Cross. For he alone understands what sin is, who knows that his sin is forgiven him. And on the other hand we may realize that the price is paid on our behalf, so that we are acquitted of sin and its consequences. We are no longer address and regarded by God as sinners, who must pass under judgment for their guilt. We have nothing more to pay. We are acquitted gratis, sola gratia, by God’s own entering in for us.”
