How do you suppose you would go about witnessing to Muslims Og, if you knew any?

That's my cup o' tea. If you ever want to learn how to respond to Muslim objections to Christianity, let me know. 

The fact is however, that Protestants are crippled to that end because both Muslims and Protestants are people of the book. Therefore they can interpret their book anyway they want. Without an authority appointed by God, they simply blow on every wind of doctrine and can prove nothing to each other.
