In the work of the Gospel "plowing" involves preparing people to receive the seed of the Gospel. As we have already seen, this can be accomplished by our godly life and good works. While plowing is an important part of Gospel work, it should not be confused with planting - putting the Gospel into a heart by speaking.
The Gospel is good news. Good works and a godly life certainly help facilitate that message, but they cannot fully communicate the truth that Christ died for our sins, was buried, and rose again on the third day. Nor can our works and life tell people what they must do in order to be saved (repent and believe).
Faith comes by hearing, hearing comes by the Word of God, and the Word of God comes by a preacher (Romans 10:14-17). As Gospel laborers, we must be willing to open our mouths and speak the Word of God to the people around us. Without this, we may end up like the farmer who has a nicely plowed field but no crop!
You do not have to be an official preacher who stands in a pulpit and speaks to a congregation to plant the seed of the Gospel. You can be the kind of preacher that shares Christ over coffee, in the break room at work, or with neighbors at your dinner table. With this in mind, ask God to give you opportunity and boldness this week to plant the seed of the Gospel in someone's heart!
