I was born with one near sighted and one far sighted eye. My brain adapted to this condition so I have not needed reading glasses until my 56th year. For me this is a metaphor for the spiritual life. We must be both near and far sighted. As Christians we are to live in the world but not be of the world and our vision must reflect that bifurcation We are to keep one eye on the game and one eye on the prize.
At Christmas earth is joined heaven and heaven is joined to earth. In Epiphany Christ is revealed to the world. The church is at community of the baptized who are be the sign of God’s love in the world.
This requires a supernatural perspective and that is a gift of grace.
