Outside Madrid stands an ancient monastery where the kings of Spain have been buried. The architect designed an elongated arch so flat that the reigning monarch insisted it could not hold the structure above it.

Against the architect’s protest, the king ordered that a column be placed underneath the arch as a safety precaution. After the king died, the architect revealed that he had deliberately made the column a quarter of an inch too short—and the arch had never sagged!

Nothing need be, or can be, added to the finished work of Christ on Calvary to sustain the weight of the world’s salvation. Our Savior’s cry from the cross, “It is finished!” (Jn. 19:30), is a translation of a single Greek word which more literally could be rendered as “Ended!” “Completed!” or “Accomplished!”

That one word tells of the greatest miracle our Lord performed, the work of redeeming a lost world. Because our redemption was perfectly finished, it is impossible for us to add even one submicroscopic work of our own to what was already done on the cross.

With utter assurance, then, we can rest our eternal hope on that one all-important word, “Finished!”
