The question of why evil exists is not a theological question, for it assumes that it is possible to go behind the existence forced upon us as sinners. If we could answer it then we would not be sinners. We could make something else responsible...The theological question does not arise about the origin of evil but about the real overcoming of evil on the Cross; it ask for the forgiveness of guilt, for the reconciliation of the fallen world

We are torn out of our own existence and set down in the midst of the holy history of God on earth. There God dealt with us, and there he still deals with us, our needs and our sins, in judgment and grace.

Being a Christan is less about cautiously avoiding sin than about courageously and actively doing God's will.

Only he who believes is obedient and only he who is obedient believes.

A day without morning and evening prayers and personal intercessions is actually a day without meaning or importance.

Human love is directed to the other person for his own sake, spiritual love loves him for Christ's sake. Therefore, human love seeks direct contact with the other person; it loves him not as a free person but as one whom it binds to itself.

Discipleship means adherence to Christ and, because Christ is the object of that adherence, it must take the form of discipleship. An abstract theology, a doctrinal system, a general religious knowledge of the subject of grace or the forgiveness of sins, render discipleship superfluous, and in fact exclude any idea of discipleship whatsoever, and are essentially inimical to the whole conception of following Christ....Christianity without the living Christ is inevitably Christianity without discipleship, and Christianity without discipleship is always Christianity without Christ.
