The essence of the Epistles of Paul is that Christians should rejoice at being deemed worthy to suffer for what they believe. The projection of a social gospel, in my opinion, is the true witness of a Christian life. This is the meaning of the true ekklesia — the inner, spiritual church. The church once changed society. It was then a thermostat of society. But today I feel that too much of the church is merely a thermometer, which measures rather than molds popular opinion.
