Well that is really Silly.
I spent many years in Christian Theology read the Bible 11 times.
I chose on my free will to study the Catholic Churches teachings.
Can't go wrong with 2000 years on the rock.
Take a good Catechism class and decide for yourself, it is your free will. Yes?
There's an enormous difference between what you described earlier as "knowing in your head" (taking classes) and experiencing Jesus. Yes, lots of people read the Bible, but reading the Bible doesn't make you a Christian. Adopting a set of beliefs does not make you a Christian either.
It's funny: People who have experienced Jesus, his overwhelming love and peace, and his life-transforming power... they preach Jesus.
People who have studied theology and catechism... they preach theology and catechism.
It is the difference between being told, and believing, that honey is sweet, and tasting and experiencing honey for yourself. I respect someone's free will and faith to believe honey is sweet. But when people ask them to defend this, it is senseless to do so on the basis of what you've been taught. You can't relate the taste of honey from the venue of the senses to the vene of the intellect. it must be experienced. Instead, you give them a taste of honey.
If someone wants to know who Jesus is, a] share his gospel, and b] act on his behalf by showing them his unfailing love, compasion, forgiveness and self-sacrifice. "Defending" your faith by sharing your book knowledge is not what people need.
They need Jesus.
