Faith or Fiction?

There's a pretty big Muslim population at my school and today it so happened that I got into a conversation with one of them, a boy named Muhammad. We were discussing religion and how he finds Christians to be less than passionate about their faith.
He of course wasn't speaking of all Christians; he just happened to notice that many of them can't find support for their beliefs in the Bible because they aren't well versed in it. And he's right. Many Christians can't reference specific parts of the Bible. Even fewer have read it cover to cover. In reality, many Christians only claim that as their faith because it's what they were born into. I know that's true for me. When I was born, my parents baptized me in the Roman Catholic church and I have been ever since.
Muhammad made great points about how straightforward the Koran is and how Jesus is a prophet rather than a member of the Trinity and why he deems it to be most logical religion there is.
I'll admit that after my conversation with him I was left baffled. I didn't know how to prove any of the things I had been taught to be true in all my years of Catholic schooling (13 going on 14).
Well Muhammad, I've been thinking about it all day and I finally have my answer:
I don't need to prove it. I don't need to fight you and deliver cold hard evidence that Jesus Christ was truly divine and truly man. I don't need to explain that the Trinity exists. I don't need to dig through the Bible to find clear times where Christ was obviously more than a prophet. I just know.
I know that that doesn't hold much weight for you and that all the evidence in the Koran is enough for anyone to believe that the Muslims have had everything figured out since day one (hell they knew the earth was round lifetimes before we even knew the solar system wasn't geocentric), but I just know.
I know because I came to these conclusions myself. I may have been born into this religion but I made it my own. I had all your questions in my head years ago and there's still so much I'm unsure of but I believe what I've been taught.
It's so great how sure you are of your religion and how deeply you trust it and I believe that Islam is true for you in the same way that Catholicism is true for me.
Catholicism is the best medium for me to praise God. I may not know the Bible backwards and forwards, I may disagree with the Vatican on certain points but I know this is the only way I know how to live. My faith has allowed to me have a relationship with God and really feel his presence in my life and I wouldn't have been able to do that if it weren't for the Catholic practices I've been doing my whole life.
God has called me to be his and I pray I can always find ways to walk in His light.
