A state government can shut down stores and theaters on Sunday, but it cannot compel worship. It can arrest and punish KKK murderers but cannot cure their hatred, much less teach them love. It can pass laws making divorce more difficult but cannot force husbands to love their wives and wives their husbands. It can give subsidies to the poor but cannot force the rich to show them compassion and justice. It can ban adultery but not lust, theft but not covetousness, cheating but not pride. It can encourage virtue but not holiness.
The point is that Christians should not look to government to affect change. Churches and Christians should be agents of positive change, one community and person at a time. And Yancey argues that our primary weapon in that process of change isn't power, or even truth. It's grace.
I give Yancey's book 4 stars out of 5. Well worth your time to read. Give it a shot.
I picked up some new books today. You'll be hearing about them soon.
