Short mission trips, like when Jesus sent his disciples to towns to spread the gospel, can open our eyes to God's heart for all people. Participating in missions can change our hearts and give us a bigger vision for God's work. Missions help some people receive a clear call to pastoral or missionary work, serve God more passionately in their home church, see God's work in new places and people, and better understand God's plan and purposes for the world. God's heart is for missions as salvation for all people, as Jesus was the first missionary who came from heaven, and missions is about God and his kingdom, not ourselves.
