Her youth pastor told her that Jesus didn't care about world peace, only the apocalypse. He didn't care about the wellness of the body, only the soul. He didn't care about the people of other faiths, only Christians. He didn't care about art and culture. He didn't care about ecology; the planet was going to burn anyway. And he didn't care about the integration of science and her faith. And the reason she could be sure Jesus didn't care about these things is because none of these things were mentioned in the Bible. Jesus just wanted her to pray, read her Bible and tell others about him. But eventually the tension between the real world and this fabricated youth-pastor's world snapped. In order to be true to herself and her passion about these issues, she had to abandon the other-worldly Jesus she'd known. Christy is an example of tens of thousands of Christians who have learned to disassociate a thin Jesus from their own wellbeing, along with the wellbeing of society. Even now that she is suicidal and struggling with clinical depression, Christy won't turn to Jesus because she believes he doesn't care.
Is that what we deduce from Scripture simply because Jesus 'never mentions" nutrition, ecology, globalization or pluralism? Jesus doesn't mention cars, light bulbs, toilets, burritos or televisions, but Western Christians seem to have no problem using these and incorporating them into their lifestyles. Wise believers learn to think Christianly and apply Jesus' teachings to all areas of their lives.
