During the last year or so, I have come to appreciate the “worldliness” of Christianity as never before. The Christian is not a homo religiosus but a man, pure and simple, just as Jesus became man… It is only by living completely in this world that one learns to believe. One must abandon every attempt to make something of oneself, whether it be a saint, a converted sinner, a churchman, a righteous man, or an unrighteous one, a sick man or a healthy one… This is what I mean by worldliness — taking life in one’s stride, with all its duties and problems, its successes and failures, its experiences and helplessness… How can success make us arrogant or failure lead us astray, when we participate in the sufferings of God by living in this world?
