In this message, David Barton calls upon Christians to take seriously their responsibility to be salt and light in the civil arena based on Christ's command "Render to Caesar the things that are Caesar's, and to God the things that are God's" (Matt. 22:21). He shows through historical examples and modern statistics the impact Christians can have on society, both for stemming the tide of evil and for promoting good, when they understand and carry out their civil responsibilities.
