Isaiah chapter 50 gives us a clear and powerful description of the servant, this suffering servant, and it tells us that the primary role of the servant is to pay attention to the weary. His followers realized that they could now tread the same path, the one of service. His followers tread his path precisely because the same God who had called Jesus, had called them. The role that Jesus played as the suffering servant, to serve humankind, that role was passed down to his disciples who in turn passed it on to those who would come after them. This is now a path we tread.
