I am surprised we are still reading about Christians arguing that not allowing them to discriminate is restricting their "religious liberty." I am disappointed and embarrassed by Christian business owners fighting for the right to refuse service to people they don't agree with. Now we have several states trying to pass laws that allow businesses to discriminate under the guise of "religious liberty."
Saying it violates your religious liberty to serve someone with whom you don't agree with is ridiculous. How is your religious liberty violated by making a cake for someone who is gay? No one is asking you to be gay. No one is saying you have to agree with the gay people you are doing business with. No one is saying when you make this cake you must profess your support for gay people. It's a cake! It's not a religious statement--but it could be, in a very different way.
If you are a follower of Christ, you violate the principles of your faith when you refuse to serve someone. Jesus never said separate from the world and only interact with those who are like-minded. Jesus said over and over to love your enemy, feed the hungry, heal the sick, give your shirt, walk a mile with someone...serve your fellow man.
It is sad that many would rather turn their back on someone, because they don't agree with them, than take the opportunity to bless someone's life.
If the goal is to point people to Jesus (and if you call yourself an evangelical Christian, it should be); than which accomplishes this better:
1. Refusing to serve someone because you think they are wrong, or...
2. Moving into someone's world and providing them exceptional service, or selling them a top-quality product, or serving them with kindness--showing them that Christians love people and do things with excellence and want to love and serve and invest in the lives of all people?
Seems pretty clear to me.
