Following the spirit of being ingenuous (or brutally honest) I want to ask the question, why do we believe in Christianity to start with?
We all have the notion that we believe what we do because we are smart people and that we have used a series of logical deconstructions of the possible belief systems, and arrived at Christianity as the most logical. But the truth?
The truth is, that in about 99% of the time, we believe in Christianity because of social coercion. More specifically, we were raised in Christian homes, in a Christian society and it was expected that we believe this way.
You hear urban legends, and some of them might be true, where someone searches the world for the correct belief system. They analyze each one carefully, then decide that Christianity the better argument . . . and then they convert. But this later case must be extremely rare.
The intellectual exercises of apologetic then comes to the Christian, in the same way to the atheist or other completely secular persons, is just window dressing. For the Christian, they start with the premise that Christian must be true, then they go through the discussion to prove it is true (and of course they will end up where they set to end up). The Atheists are no better. They start with the premise that Christianity can't be true . . .and of course their intellectual exercise ends them up exactly where they intended to end up.
I'm not saying that this has to be a bad thing, but just exposing it for what it is. Many of my Christian friends take the intellectually easy path at that point. That is, it is God's sovereignty. It goes like this. If God is totally in control, and predestines you to be a Christian, then He has orchestrated each step of the way for you. You were born in the shadow of the church building and you were taught Christianity (rather than being born in Jedda and being taught Islam) because God has his finger on you from the beginning. There is comfort in thinking that way. I am a "Reformed" Christian, speaking theologically and this is consistent with what we believe. It certainly could be true and I hope that it is.
But this is a logical "cop-out" as they would say in the sixties . . . or seventies. But, once again, it doesn't matter if Christianity is true or if it is true that God is completely sovereign over you spiritual orientation.
But for the young person, truly seeking for truth, this becomes a stumbling block. It starts as stumbling block when they first meet a real-life Mormon . . . or a Muslim, who equally believes that God put them in the their faith because He loves them and chose them to be "believers." But those positions are safe.
For some of us, the desire for truth is so overwhelming, that we are willing to dine with the devil. We are willing to sit at tea in "Doubter's Castle" and not just sip the tea, but read the books in its library. We take the risk of actually leaving the faith in order to save it.
A long time ago when I first started my walk to find truth, I remember my old Navigator boss giving me a stern warning, "I knew a man who did what you want to do . . . he isn't a Christian anymore?"
I knew that I had to take the chance. I took the chance, not because I'm a risk taker just for the fun of it. It did it because I had no choice. That boss had just spent the previous two years being very abusive to my family and me. In the midst of all of that, the "wonderful, godly" self, revealed its dark side of rage, anger and depression. The Christian ground I was standing on was crumbling under my feet. I had to take the journey. The default or passive position would have been to completely loose my faith.
But I'm still not one of those rare people who search completely objectively. Even though I wanted to know truth with all my heart, I was still biased. I was still rooting for Christianity to prove itself.
So, before I go further in this discussion, I just wanted to honestly explore this intellectual, psychological and spiritual bases for why we believe anything.
