In the farming metaphor of Gospel work, fields represent people. It is into the hearts of people that the Gospel seed is sown. There, by the grace of God, it germinates, takes root, and begins to sprout. People who have been instructed in the Gospel and are ready to repent and believe are like a field of grain ready to be gathered in to eternal life!
The people in our lives can be grouped together in relational categories. These categories can also be considered "fields". Consider the common fields listed below.
Family Field: people in your immediate and extended family.
Neighborhood Field: people who live beside or near you.
Workplace Field: people with whom you work.
Community Field: people you see on a regular basis as you shop and eat out.
Recreation Field: people with whom you play sports, go fishing, hunt, golf, etc.
Stop and think about your fields. You may not have a connection to every field in the list above. Some of your fields may be larger or smaller (represent more or less people) than the fields of others. However, your fields are by divine appointment and they represent potential fruit for the Kingdom of God. Are you working them for the Gospel?
