In this world, it is very rare—impossible, even—to find something without blemish.
The same can be said of the Old Testament sacrifices—they were not perfect. They did not purify anything and never truly dealt with sin and judgment. But when we look at the sacrifice of Jesus, the most pivotal moment in history, we witness something that is faultless. Hebrews 9:23-28 shows us that Jesus’ sacrifice was perfect.
“Therefore it was necessary that the copies of the things in the heavens should be purified with these, but the heavenly things themselves with better sacrifices than these. For Christ has not entered the holy places made with hands, which are copies of the true, but into heaven itself, now to appear in the presence of God for us; not that He should offer Himself often, as the high priest enters the Most Holy Place every year with blood of another—He then would have had to suffer often since the foundation of the world; but now, once at the end of the ages, He has appeared to put away sin by the sacrifice of Himself. And as it is appointed for men to die once, but after this the judgment, so Christ was offered once to bear the sins of many. To those who eagerly wait for Him He will appear a second time, apart from sin, for salvation.”
