The Great Commission calls Christians to be Christ's ambassadors, whether serving internationally or locally. When we obey God's call to serve, we not only impact others but experience spiritual growth ourselves. Faith strengthens through exercise, just as our bodies do. God typically reveals His plan one step at a time, requiring us to take that first step of faith before seeing the next. Throughout Scripture, we see examples of those who followed immediately (like Andrew, John, and Matthew) and those who stepped back (like the rich young ruler). By overcoming our fears and stepping into ministry, we experience God's goodness firsthand and grow closer to Him.
