God gave specifications that the blemished are not to serve or go near the curtain in the tabernacle. God is a perfectionist! At Jesus’ crucifixion the curtain in the temple was torn from top to bottom. Jesus made a new way for us through Him. Now we have confidence to enter even the Most Holy Place, no matter how "blemished" we may seem.

Mark 15:37-38
With a loud cry, Jesus breathed his last. The curtain of the temple was torn in two from top to bottom.
Heb 10:19-20
Therefore, brothers, since we have confidence to enter the Most Holy Place by the blood of Jesus, by a new and living way opened for us through the curtain, that is, his body,

The high priest was to keep himself "clean" in order to serve in the holy place of the tabernacle. Since we as Believers are "tabernacles" for the Holy Spirit, shouldn't that make us want to remove ourselves from anything "unclean" or sinful in order to serve HIM?

Lev 22:1
The Lord said to Moses, "Tell Aaron and his sons to treat with respect the sacred offerings..." 
How would we do that today?  How is the money spent coming into our churches today?  Is it spent for sinful purposes? Ex. salaries for lesbian pastors???  Would this be treating with respect the sacred offerings?

The commentary under Year of Jubilee - Lev. 25, we find these words, "One of the most remarkable features of the Jubilee is the concept of redemption...." The commentator mentions it is a "foretaste of even greater spiritual redemption in the era of the Messiah." Wonder if the year of Jesus' crucifixion was a year of Jubilee and/or will His return be in a Jubilee year?
Lev 25:10
It shall be a jubilee for you; each one of you is to return to his family property and each to his own clan.
There will be a gathering of the nations into the millennium.

In addition to the weekly Sabbath for rest and worship, God also commanded that there was to be a rest for the land on each seventh year. But...not to worry. He made sure that they would have enough in the sixth year to more than make up for the fallow seventh year.

Lev 25:21
I will send you such a blessing in the sixth year that the land will yield enough for three years.

Isn't that just like God? When we obey Him completely, he blesses us abundantly!
