Then, we are to understand the action taken in comparison to a harvest. Consider the following passage. He told them, 'The harvest is plentiful, but the workers are few. Obviously, the Lord was speaking figuratively. One who plows a field in the manner they did in Jesus' day has to keep their eyes ahead or the rows plowed will be crooked.
Crooked rows are inefficient, representing poor stewardship of the field.
One who plows in the Lord's field in this manner is not fit for service in the kingdom of God. This is the first thing Jesus commanded the 72 to do when He appointed them and sent them into the field. They are ripe for harvest. Others have done the hard work, and you have reaped the benefits of their labor. Jesus was speaking figuratively to indicate that there were many people who would believe the message of the kingdom it were presented to them.
