Jesus knew the difference. Jesus was not presented to the world as God's Public Relations agent. He came to transform us morally no matter the cost - to Him or to me. Success makes us feel good, victory makes us feel right. If riches constitute a sort of spiritual success or divine approval then Christ's simplistic lifestyle proves Him a failure.
Success is a cheap substitute for victory.
Where the church necessarily touches the world there will also be business transactions essential to the church's welfare. Even Jesus had a bag of money, which Judas carried, to care for the practical needs of His faithful band. Today the business methods of the church are based on simple honesty and have very little in common with the business psychology methods of the business world. What business principles of the world may apply to the business of the church must be watched and kept properly at the perimeter of the church's activities. But if that spirit penetrates to influence the spiritual leadership of the church it may indeed produce a visibly successful church.
