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.
Dietrich BonhoefferThe earthly form of Christ is the form that died on the cross. The image of God is the image of Christ crucified. It is to this image that the life of the disciples must be conformed; in other words, they must be conformed to his death (Phil 3.10, Rom 6.4) The Christian life is a life of crucifixion (Gal 2.19) In baptism the form of Christ's death is impressed upon his own. They are dead to the flesh and to sin, they are dead to the world, and the world is dead to them (Gal 6.14). Anybody living in the strength of Christ's baptism lives in the strength of Christ's death.
Dietrich BonhoefferWherever it pleases God to put man in this world, the Christian must be ready for martyrdom and death. It is only in this way that man learns faith.
Dietrich BonhoefferBut to procrastinate and prevaricate simply because you're afraid of erring, when others - I mean our brethren in Germany - must make infinitely more difficult decisions every day, seems to me almost to run counter to love. To delay or fail to make decisions may be more sinful than to make wrong decisions out of faith and love.
