Cheap grace is the idea that "grace" did it all for me so I do not need to change my lifestyle. The believer who accepts the idea of "cheap grace" thinks he can continue to live like the rest of the world. Instead of following Christ in a radical way, the Christian lost in cheap grace thinks he can simply enjoy the consolations of his grace.
Dietrich BonhoefferThe best-informed man is not necessarily the wisest. Indeed there is a danger that precisely in the multiplicity of his knowledge he will lose sight of what is essential. But on the other hand, knowledge of an apparently trivial detail quite often makes it possible to see into the depth of things. And so the wise man will seek to acquire the best possible knowledge about events, but always without becoming dependent upon this knowledge. To recognize the significant in the factual is wisdom.
Dietrich BonhoefferChristian community is like the Christian's sanctification. It is a gift of God which we cannot claim. Only God knows the real state of our fellowship, of our sanctification. What may appear weak and trifling to us may be great and glorious to God. Just as the Christian should not be constantly feeling his spiritual pulse, so, too, the Christian community has not been given to us by God for us to be constantly taking its temperature.
Dietrich BonhoefferThe 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
