A church must be more deeply and practically committed to deeds of compassion and social justice than traditional liberal churches and more deeply and practically committed to evangelism and conversion than traditional fundamentalist churches. This kind of church is profoundly counter-intuitive to American observers. It breaks their ability to categorize (and dismiss) it as liberal or conservative. Only this kind of church has any chance in the non-Christian west.
Timothy KellerSome suffering is given in order to chastise and correct a person for wrongful patterns of life (as in the case of Jonah imperiled by the storm), some suffering is given not to correct past wrongs but to prevent future ones (as in the case of Joseph sold into slavery), and some suffering has no purpose other than to lead a person to love God more ardently for himself alone and so discover the ultimate peace and freedom.
Timothy KellerTo preach the gospel is to show people their need for salvation against a backdrop of God's nature and the character of sin, and then present Jesus as the only remedy for what ails them and the world. In my weekly preaching in the worship services I always call people to believe in Christ.
