George Chin discusses six practices of missions involvement: going, praying, sending, mobilizing, welcoming, and learning. Each practice plays an important role in fulfilling the Great Commission to make disciples of all nations. The document provides examples of how individuals can participate in each practice, from going on short-term mission trips to financially supporting missionaries to learning about different countries and cultures through reading. It emphasizes that through these various practices, all Christians can contribute to God's work of spreading the gospel around the world.
