I checked the indian BMV website, I did'nt see a plate for Christians, or pro life. They do offer "In God we trust" plate which generated some controversy a few years ago.
From the Indiana BMW website:
"Show your support of Indiana Youth Groups services and programs for lesbian, gay, bisexual, transgender and questioning youth and their allies. By purchasing this plate, you will help fund programs at the IYG activity center, build capacity for Gay Straight Alliances in high schools around the state, and assist other communities in forming their own youth services. Show the world that you care about LGBT youth and their futures."/
