The “yoke” Jesus refers to in Matthew 11 is well illustrated by the process of training a young bullock to plow. In some parts of the world, the farmer will have the young bullock harnessed to the same yoke as a mature ox. The bullock, dwarfed by the other animal, will not even be pulling any of the weight. It is merely learning to walk in a field under control and with a yoke around its neck; the ox pulls all the weight. It is the same when a believer takes Christ’s yoke. As the Christian learns, the yoke is easy and the burden light.
