Advent is a season of expectation, hope, and impending joy based on faith. Both our readings strongly capture this theme.
The prophet Isaiah addresses a people of lost identity and little hope set against a gruesome world and presents a very ideal series of obviously impossible transformations that can be attained only by God. Isaiah goes on to promise that all these things will come to pass, and challenging the people to return to faith in God, their identity.
Our Gospel reading carries this theme into the new covenant in the person of the blind men who, while not having the same theological definition as we do, recognize in Jesus, the power to do the seemingly impossible. Jesus asks for expression of faith. Do you believe that I can do this?” They respond emphatically, “Yes, Lord.” Jesus responds, “Let it be done for you according to your faith.”
