How does a Christian know if he’s truly called to missions—and once called, how does he decide where to go? In past centuries, the options were limited and often chosen by circumstance, but today the opportunities seem overwhelming. Should a missionary simply follow desire, or are there clearer biblical marks of calling? And with thousands of unreached people groups worldwide, how can one wisely narrow the field? This episode explores the essential questions every aspiring missionary must ask and offers a framework for discerning both calling and location in light of Scripture, history, and global need.
