There are two difficult realities you must accept if you are to live faithfully as a Christian in the world. (1) You will have enemies. And (2) you must love those enemies. Jesus taught both things quite clearly.
This is a good, hard question. The way we answer it will both reflect and inform our understanding of justice and mercy.
In the book of Joshua God commands Israel to slaughter the Canaanites in order to occupy the Promised Land. It was a bloody war of total destruction where God used his people to execute his moral judgment against his wicked enemies. In moving toward an answer it will be helpful to think carefully about the building blocks of a Christian worldview related to God’s justice and mercy.
You don’t have to leave home to be crazy on fire for the Lord. Jesus spent his first thirty years simply working and obeying. This tells me that it’s possible to be radical while changing diapers, or creating spreadsheets, or plowing snow, or doing whatever mundane task you are called to. For the Christian, there is no such thing as insignificant work.
David Murray with a good word for all of us who love the workahol:
Tony Schwartz took a year of 10-hour days to write each one of his first three books, but only six months of 4-hour days to write his fourth and fifth. His secret? He took more time off!
