If only we were as honest today...no pleading, begging, cajoling to get people to "give their heart to Jesus" in that statement. Just the plain, bare truth that it will cost you something—nay, everything!—should you decide to follow Jesus. Kind of reminds you of the rich young ruler in the gospels, doesn't it? He ended up walking away, but at least he didn't have a deluded sense that he was following Jesus.
Perhaps the first step in becoming a Christian is to realize that you aren't one yet...at least not if anything other than Jesus is at the center of your life, that is.
Too radical an idea? Perhaps, but you can't say it isn't a biblical one!
