This verse is talking about evangelism. The disciples are the ones who was talked about here. They spread out the good news to the people in the villages, proclaiming His greatness. And, the disciples were really eager to do evangelism in the community.
Let us be like the disciples. Don't be ashamed of the gospel. Spread the Good News so that the people will be saved and experience eternity. It is indeed a great reward when we bring lost souls in His throne. It is a victory party in Heaven. So, spread the Good News in your community.
