The Gospel this Sunday tells us the story of Martha and Mary. Martha is "burdened with much serving" and is "anxious and worried about many things" whereas Mary just "sat beside the Lord at his feet listening to him speak."
In the Gospel today, Jesus tells us that the harvest is abundant but the laborers are few. This means that there are lots of people out there who want to enter the Kingdom of God and become Catholic but very few have the courage to actually share their faith.
