“All the passages in the Holy Scriptures that mention assistance are they that do away with "free-will", and these are countless…For grace is needed, and the help of grace is given, because "free-will" can do nothing.”

“For a time
I rest in the grace of the world, and am free.”
"The Peace of Wild Things" in Green River Review, No. 1 (1968).

And I feel above me the day-blind stars
waiting with their light. For a time
I rest in the grace of the world, and am free.

Costly Grace
Context: Cheap grace is the deadly enemy of our Church. We are fighting to-day for costly grace. Cheap grace means grace sold on the market like cheapjacks’ wares. The sacraments, the forgiveness of sin, and the consolations of religion are thrown away at cut prices. Grace is represented as the Church’s inexhaustible treasury, from which she showers blessings with generous hands, without asking questions or fixing limits. Grace without price; grace without cost! The essence of grace, we suppose, is that the account has been paid in advance; and, because it has been paid, everything can be had for nothing. Since the cost was infinite, the possibilities of using and spending it are infinite. What would grace be if it were not cheap?
