While two visitors were visiting Annapolis, they noticed  several students on their hands and knees assessing the  courtyard with pencils and clipboards in hand. "What are they  doing?" one of them asked their tour guide.

"Each year," he replied with a grin, "The upperclassmen ask  the freshmen how many bricks it took to finish paving this  courtyard."

"So what's the answer?" one of the visitors asked the tour guide when they were out of earshot of the freshmen.

The guide replied, "One."

That brings up an interesting theological question. How many  sacrifices did it take to finish paying for our sins?  The Jews  would have needed lots of pencils and clipboards to make the  calculation.  "Let's see, let's take all the sin offerings, all the  guilt offerings, the bulls, the goats, the lambs, the  turtledoves......"

So what's the answer?  How many sacrifices did it take to  finish paying for our sins?  Only one.

"And every priest stands ministering daily and offering  repeatedly the same sacrifices, which
can never take away sins.  But this Man, after
He had offered one sacrifice for sins forever,
sat down at the right hand of God."
(Heb. 10:11-12)

After thousands and thousands of sacrificial animals had been sacrificed, Jesus Christ gave his own life on the cross.  Only then could it be said,

"It is finished."
(John 19:30).
