Christ in person took up the cross, and there was a curse in it when he took it up: he takes off the curse, and leaves it; and bids you take it up next. O believer, the tree is left thee, but the curse is away; the nails are left, but the venom they were dipped in is away. Though bulls should push you, the horns wherewith they pushed him are cut off. Though crosses of all sorts should meet together in your case, the soul and life which the fiery law breathed into them is gone.
