Joshua Harris, Marty Sampson, and Mckrae Game. They've done some thinking and the church is not happy about it. We say "welcome to the beginning of feeling okay about looking for answers." Y'all ballers.
Joshua Harris renounced Christianity close to the time the author of I Kissed Dating Goodbye announced his separation from his wife. Since then, he looks like he's living life and staying away from doing much other than concentrating on his kids, work, and loving those he no longer judges.
Marty Sampson was a singer and writer with Hillsong, a blockbuster Christian singing group. His deconversion has been more public due to his Instagram account. 
Lastly, there's the most recent story from McKrae Game, the head of a conversion therapy program who has come out as gay.
No judgement here. We've been through what they have. And we look forward to more people simply asking the questions that are down deep.
