Jesus offered His Blood once.

​“nor was it that He would offer Himself often, as the high priest enters the holy place year by year with blood that is not his own. Otherwise, He would have needed to suffer often since the foundation of the world; but now once at the consummation of the ages He has been manifested to put away sin by the sacrifice of Himself.”

‭‭Hebrews‬ ‭9‬:‭25‬-‭26‬ ‭NASB1995‬‬

The priests entered the copy of the Holy of Holies with the blood from an animal. Jesus entered the true Holy of Holies with His blood to make atonement for all sins once and for all of eternity past, present, and future. He will never have to apply His blood to the altar again. 

“For the death that He died, He died to sin once for all; but the life that He lives, He lives to God.”

‭‭Romans‬ ‭6‬:‭10‬ ‭NASB1995‬‬

“For Christ also died for sins once for all, the just for the unjust, so that He might bring us to God, having been put to death in the flesh, but made alive in the spirit;”

‭‭1 Peter‬ ‭3‬:‭18‬ ‭NASB1995‬‬

And now we are waiting on Him to return to earth to collect for Himself “whosoever will call on his name to be saved.” Will that be found to be true in you and me?

“For whosoever shall call upon the name of the Lord shall be saved.”
