Inevitably, as most committed Christians will encounter, we bump up against topics that create angst or uncertainty.Whether it's approaches to injustice that involve troubling forms of violence, or exorbitant amounts of money spent on seemingly trivial matters, or the presence of vastly differing beliefs around issues of personal morality, much in the world creates tension for the follower of Jesus, let alone a young adult in general. And really, it should (the whole New Testament is about navigating such tension after all).
It's often assumed by both Christians and non-Christians that the Bible is one long narrative (or rule book) about not getting too close to "them." And yes, there are warnings - e.g. intermarrying in ancient times or adopting pagan rituals in Roman times - but we risk equating these warnings with a complete disengagement and lack of presence with those who are different. We forget where Jonah's fear got him.
A fear of difference wasn't the way of Jesus. He was known as a friend of sinners for a reason - he was actually their friend. Literally. We hear the word "pagan" or encounter people who are different and feel discomfort or even fear towards "them." Perhaps we even feel justified in our judgment and avoidance, forgetting all the while that the label "pagan" is preceded by the encouragement to "live such good lives among the pagans" (1 Pt. 2:12). Among=presence.
The tension between the way of Jesus and the way of world cannot be easily navigated or reconciled, I'll admit. But fear cannot be our response to difference either. Like Jonah, we are sent into the places of difference to be a presence - friends - with those we differ from. And like Jonah, we cannot refuse this call. This is the way of Jesus. This is the way we are sent beyond a fear of difference:
I have given them your word and the world has hated them, for they are not of the world any more than I am of the world. My prayer is not that you take them out of the world but that you protect them from the evil one. They are not of the world, even as I am not of it. Sanctify them by the truth; your word is truth. As you sent me into the world, I have sent them into the world. (John 17:14-18 NIV).
