Priest and his duties

Ezekiel 44:1-31
Levites can't not serve in the sanctuary before the Lord for they have to bear their consequences of their sin.
The priests, who are Levites and descendants of Zadok and who faithfully carried out the duties of the sanctuary when the Israelites went astray from God. They alone are to enter God's sanctuary before God ad perform the service.
The priests are to serve as judges and decide it according to my ordinances.
Why?
The Lord let his servant who keep his duties of the sanctuary and regulation serve Him. It is not all Levites but the one who follow his commands.
It is still envisaged in earthly terms: there is still a Temple and sacrifices; the people of God are synonymous with Israel, the laws continue, so does death, so does the need for a sin-offering.
Minister or pastor, elder is the priest in these generation, who serve the Lord and earn from brothers offering in church. They have their duties have to serve the Lord and serve as judges and obey the command of the Lord.
How?
Am I a priest now? A part time priest? Not really, May my life could be used for the Lord and glory his holy name. It could be done in my daily life.
