About
Belle Liu
Belle Liu is an evangelist and apologist whose work centers on one conviction: the claims of Jesus can bear the weight of any honest question.
What began as personal wrestling with doubt became a public ministry. Belle now spends her weeks in street conversations, on campuses, in churches and online — where millions encounter the case for Christ every month, many of them from Muslim backgrounds who have never been given a respectful answer.
Through Christ Underground she has trained 19k+ believers across 100+ countries: ex-Muslims stepping into their calling, missionaries preparing to go, and ordinary Christians who simply want to stop freezing when the hard question comes.
“Equipping Minds. Reaching Nations.” is not a slogan. It is the order of operations.
