When a student serves on a mission trip, he or she will often get a glimpse into the heart of God. We serve a big God that has amazing  plans for his people and the nations. While on a short-term mission trip, students sense God's amazing compassion for "every tribe and tongue and people and nation" (Revelation 5:9). Once one grasps the compassion of God, it becomes easier to engage in Kingdom-building. The Great Commission, as outlined in Matthew 28, is not a suggestion; it is a command. We must be willing to accept the calling that God has placed on our lives.
