i agree with leading by example...

when i was a freshman in college, there was this christian cat that lived across the hall from me. he was real cool, real mellow...just seemed to have it all together. and i knew him for months before the subject of religion even came up. but just by the way he carried himself - no cursing, no excessive partying, etc - it just made me curious as to what was his motivation/inspiration...

one day the subject of religion came up, he told me he was a christian, and that started a series of discussions, lol. but to me...dude was probably the best example i have seen of how a christian is supposed to live. he didn't make a big spectacle of his beliefs, but lived his life in accordance with the Bible and it definitely shined through. i think that attracts folks a lot more than the Bible thumping...
