Many have been taught that this scripture means the anointing will break a yoke after it has already been placed on a person. However, this diminishes the full weight of the verse. The anointing spoken of here is not merely reactive; it is powerful enough to make a yoke unable to touch you at all.
Consider the difference between maintenance and prevention. Would you rather a yoke be placed on you and then broken off, or would you rather be yoke-proof? The comparison is similar to healing versus divine health. Healing restores what sickness damaged, but divine health prevents sickness from taking hold in the first place. One is good; the other is superior.
When the anointing is present and active, oppression cannot settle, limitation cannot fasten itself, and burdens cannot attach themselves. This Strange Oil creates an environment where yokes cannot survive. The moment they attempt contact, they are destroyed.
