In the Christian Story, mind and matter - invisible things and visible things - are both real. The Christian view is not the only way of viewing the world, of course. It has competition.
Greg KouklThough it's hard to be completely certain about things like this, I have a suspicion that only someone with deep freedom (one who makes decisions for reasons that are his own) and who's also a moral being (can experience goodness) can have a meaningful friendship with God. If friendship with God and sharing in His happiness are good things (and it seems they are), then making a creature who could enjoy these things is also a good thing, even if it comes with a liability. There's a risk.
Greg KouklReality has a way of injuring people who don't take it seriously. If you don't believe in gravity, for example, and then step off a tall building, you won't just float away.
Greg KouklMost Christians who've been around for a while have their Story in bits and pieces, but have never seen how powerful it really is when assembled as a whole. I want them to see how well it fits together and how it offers tremendous explanatory power regarding the world as we actually find it. I want them to see how it resolves the problem of evil, and why God's solution - the God/man Jesus - is the only solution.
