Introverted seekers need introverted evangelists. It's not that extroverts can't communicate the gospel, either verbally or nonverbally, in ways that introverts find appealing, it's that introverted seekers need to know and see that it's possible to lead the Christian life as themselves. It's imperative for them to understand that becoming a Christian is not tantamount with becoming an extrovert.
