Freedom is the ability to do what you want and define life on your own terms. Christianity takes both of those away.
This is a very American (and modern) objection to Christianity. After all, the right to “life, liberty, and the pursuit of happiness” is in the Declaration of Independence. It’s in the very DNA of our country (I’m not going to get off track here and delve into politics and all that, but it’s my belief that this phrase is widely misinterpreted today and has become a selfish and superficial attitude rather than the ground-breaking statement of political freedom it was meant to be).
So when a person becomes a Christian, do they have to give up their freedom? Don’t you become a slave to one group’s view of morality? Do you have to give up your voice and become just another sheep in the crowd?
