Engaging in the mission is what it means to follow Jesus.
Summary
The sermon emphasizes that the call to be involved in God's mission is inherent in Jesus' initial call to follow him, as seen in Matthew 4:19 where Jesus made his disciples "fishers of men." This means that following Jesus intrinsically means engaging in his mission, leaving no room for passive discipleship. Therefore, the question for believers is not whether they are called to the mission, but rather where and how they will participate.
