This episode mostly focuses on the early stages of sanctification, in which new Christians are faced with the arduous task of reversing bad sowing. Many despair in the process as they discover that modifying their behavior is difficult, if not impossible. But that's the whole point of the yoke. The episode highlights the fact that all spiritual progress in sanctification is predicated on the yoke, our connection with Christ. The yoke softens our heart to the will of God, making sin distasteful. The imperative "break up the fallow ground" presumes already being yoked to Christ, which is the essential component in addressing a hard heart and the strongholds that come from it.
