From Voice of the Martyrs daily devotional

"What we do for the Lord is not just a job—it’s a mission. A mission is never about a single person’s responsibilities. It is singly focused on Christ and his kingdom. Therefore, someone at the helm of God’s work in a particular area may leave, but the mission itself never dies. God’s work is never left undone. It goes on forever to its completion. Those who are willing to undergo persecution for their faith teach us about the meaning of mission. They recognizethat there are only two things that last for eternity—God’s work and human souls. When we are willing to invest our lives in these things,we are involved in a mission with eternal significance."
