So the point of the exclusiveness of Christianity is not to show the rest of the unbelieving world that Christians are better or more moral than others. Christians are not better. Rather, the purpose is to communicate that we all share the same alienated condition as human beings and so we bring the gospel as beggars pointing other beggars to the only bread.”
As I said: In a nutshell.
Let nobody suppose that he has tasted the Holy Scriptures sufficiently unless he has ruled over the churches with the prophets for a hundred years. Therefore there is something wonderful, first, about John the Baptist; second, about Christ; third, about the apostles...We are beggars. That is true. - Martin Luther
