'One is immediately struck in 1 Peter with two contrary reactions of outsiders to the soft missionary difference. On the one hand, there is angered surprise and blaspheming from non-Christians that Christians are no longer joining them "in the same excesses of dissipation" (4:4). The Christian difference is the cause of discrimination and persecution. Moreover, 1 Peter tells us, such negative reaction is to be expected from non-Christians. Christians should not be surprised by the "fiery ordeal" which they have to endure (4:12). The negative reactions of non-Christians do not rest on misunderstanding, but are rooted in the inner logic of the non-Christian constellation of values which seem incompatible with the values of Christians. On the other hand, one of the central passages in 1 Peter entertains a lively hope that precisely the Christian difference - outwardly visible in their good deeds - will cause non-Christians to see the truth and eventually convert (2:12,15; 3:1;3:16). This expectation presupposes overlap between Christan and non-Christian constellations of values. The good works of Christians can be appreciated by non-Christians and look attractive to them.'
