J.I. Packer comments on mature evangelicals, but in many ways his comments apply more broadly to Christians in general.
Immature evangelicals have sometimes settled for a euphoric, man-centred pietism, concerned only with possessing and spreading the peace and joy of ‘knowing Christ as my personal Saviour’ (sadly, these precious words are nowadays a cant phrase), and never appreciating God’s revealed concern for truth and righteousness in church and community. Maturer evangelicals, however, have always recognized that though personal conversion is the starting-point, Christians must learn a biblical God-centredness and seek after ‘holiness to the Lord’ in all departments of the church’s worship, witness and work and in every activity and relationship of human life.*
Would that this understanding would permeate American churches!
