As I see it, a true Christian is one who puts obeying the highest righteous authority, God, first, regardless of what the Democratic Party, Republican Party, Masonic lodge, church pastors, or any other human organization or person supports.
It means putting God above the government. It means putting God above family. And yes, it means putting God above oneself.
Is anyone really a true Christian? Perhaps not. But the closer each of us comes to being true Christians, seeking to practice true Christianity, the better off things will be.
If someone put a gun to my head, asked me if I was a Christian and said that they would kill me if I was, I like to think that I'd reply something like "I try hard to do what is right, to be a follower of the best teachings, but I fall short of being a follower of the book, a true Christian. What do you think I should do to do better?"
But I think one never really knows how one will behave in a particular situation until one faces it. In reality, I might panic and deny being a Christian three times, just as Peter three times denied knowing Jesus.
