This document discusses the challenges and rewards of being a missionary. It describes the missionary profession as high-risk work that involves long hours, great responsibility before God and men, living in marginal areas, seeing doors close, tolerating insults, helping those unwanted or undeserving, taking on others' problems without recognition. However, it says all this is worth it to feel fulfilled with humanity, love, God, friendship and bring positive change. The missionary aims to share the love of God, light and hope with those most in need, as was Jesus' message of universal love.
