But the problem is that after ten years, I’m getting tired of trying to convince fellow Christians that I am, in fact, a Christian, even though I may vote a little differently than they vote, interpret the Bible differently than they interpret it, engage with science a little differently than they engage with it, and understand sovereignty and choice a little differently than they understand those things.
Just as I do not have a monopoly on determining who is and who is not a "Christian," neither do you. Anyone else who has had to field the question, "How can you call yourself a Christian?" understands not only how tiring it gets, but also how it kills your sense of community and love for the church.
