The Bible indicates the people of the world are lost and going to hell. The church has been tasked with sharing the Gospel with the world. If we don't have a heart for the harvest then we won't reach out to the world or be earnest about the outreach we do. The world knows if we truly love them or if we are just going through the motions. If we have a true heart for the harvest then we will earnestly share the gospel with the world.
