From the book "Praying in The Presence of Our Lord with Fulton J. Sheen" by Micheal Dubruiel, Fr. Benedict J. Groeschel, CFR, Series Editor and preface by Father Andrew Apostoli, CFR, Our Sunday Visitor, 2002.
The title of a chapter, paraphrasing Archbishop Sheen:
"His Work is Finished, Ours is Not."
Our Lord finished His work, but we have not finished ours. He pointed the way we must follow. He laid down the Cross at the finish, but we must take it up... He has finished salvation, we have not yet applied it to our souls. He has finished the Temple, but we must live in it....He has finished sowing the seed, we must reap the harvest...He has planted the wheat field; we must gather it into our barns.
(1953 from his work Calvary and the Mass).
