By our enemies Jesus means those who are quite intractable and utterly unresponsive to our love. - Dietrich Bonhoeffer

The cross is not random suffering, but necessary suffering. The cross is not suffering that stems from natural existence; it is the suffering that comes from being Christian. … A Christianity that no longer took discipleship seriously remade the gospel into only the solace of cheap grace. Moreover, it drew no line between natural and Christian existence. Such a Christianity had to understand the cross as one's daily misfortune, as the predicament and anxiety of our daily life. Here it has been forgotten that the cross also means being rejected, that the cross includes the shame of suffering. Being shunned, despised, and deserted by people, as in the psalmists unending lament, is an essential feature of the suffering of the cross, which cannot be comprehended by a Christianity that is unable to differentiate between a citizen's ordinary existence and a Christian existence. The cross is suffering with Christ.

God did not reckon his Son too dear a price to pay for our life, but delivered him up for us. Costly grace is the Incarnation of God. Costly grace is the sanctuary of God; it has to be protected from the world, and not thrown to the dogs. It is therefore the living word, the Word of God, which he speaks as it pleases him. Grace is costly because it compels a man to submit to the yoke of Christ and follow him; it is grace because Jesus says: "My yoke is easy and my burden is light."

By his willingly renouncing self-defence, the Christian affirms his absolute adherence to Jesus, and his freedom from the tyranny of his own ego. The exclusiveness of this adherence is the only power which can overcome evil.
