I’m too busy following Jesus to spend much time being politically conservative. There is a difference between the two goals.
Feel free to have an opinion, even a strong opinion, about immigration and illegal aliens. But don’t call your opinion Christian if it’s not in the Bible. Leviticus, in fact, talks quite a bit about aliens. You could look there.
Don’t call your opinion about war Christian if it’s not in the Bible. Yes, many people in the past have called their war Christian, most famously the Crusaders. The Crusaders don’t count. They weren’t prophets or apostles. They weren’t inspired.
Some people believe the Kingdom of God can be advanced by killing Muslims. Some people believe it can’t. Accept it as a difference of opinion. Accept it as a difference in strategy.
The saying used to be, “What’s good for General Motors is good for America.” The saying among many conservatives is now, “What’s good for America is good for Jesus.”
