Caleb Kaltenbach, author of "Messy Truth: How to Foster Community Without Sacrificing Conviction," reveals his incredible personal story, his passion for helping others show empathy — and his passion for truth. Kaltenbach, who was raised by gay parents, once wanted to disprove the Bible. He found himself saying, "I never, ever want to be a Christian." 

Then, he encountered Jesus, changed his views on marriage and is now on a mission to help people discover truth and God's love.
