I don't claim to speak for all Christianity. I speak for myself.
I have nothing to defend. I know what is true for me, and it is very, very similar to the same truth others know for themselves. There is nothing to defend. There is nothing to prove.
For you to say that I cannot, or one cannot know the truth in their heart is your opinion. Again, that is your truth. I know differently. Whoever first labelled it "a priori" understood that some things are known to be true without having proof thereof. Apparently you do not subscribe to that thought. I do.
If you have never known something is true in your heart then that is for you to say about you. But I have. And as I said before, I bet most if not all Christians have. Because that is where the Truth of the Lord is. Not the mind. Not in man's reasoning. So please, I know the experience of knowing truth in my heart. You don't. For you to say it isn't so is the same as saying anything you cannot do, no one else can do either.
..."...no matter how rationally compelling i can make an argument, i'm yet to find one christian emotionally mature enough to acknowledge it, and thus abandon, or at least seriously doubt, their faith."
Bingo! You have stated well the weakness of reasoning when confronted with the power of Faith and the Holy Spirit. Man's reasoning cannot overpower true Faith or the power of the Holy Spirit. Where is the weakness daniel... in the hearts of any Christian you have failed to influence... or in what you consider to be a rationally compelling argument? The weakness is in your argument.
All Christians choose to believe. We are free to believe or not. We have heard the arguments from all sides and are convinced to believe the Word of God over the word of man. Many of us, like myself, have proven ourselves in the arenas of critical thinking and emotional stability through our professonal pursuits and accomplishments. It is a far stretch to presume emotional immaturity because you, daniel, are unable to convince a Christian to adandon or question his Faith.
Geesh man, talk about pompous.
