From Dietrich Bonhoeffer's book Meditations on the Cross, the chapter entitled "God's Love for Human Beings".
The peace of Jesus Christ is the cross. The cross, however, is God's sword on this earth. It creates disunion...Do I love like God, or do I love like human beings? Am I embracing His love, or looking for Him to love me like humans do?
God's love of human beings on the one hand, and human beings' love of their own kind on the other, are much too dissimilar. God's love of human beings means cross and discipleship, and yet precisely as such is means life and resurrection. "Those who lose their life for my sake will find it" (Matt. 10:39)
