Under God's Old Covenant Law, priests were holy & set-apart, devoted to serving God under a high priest. Later, the apostle Peter calls the church "a kingdom of priests," quoting Exodus 19 The elements of Leviticus 8 explain what this means: every follower of Christ is a purified, prepared, consecrated, sanctified, dedicated, and inaugurated priest of God. So under God's New Testament gospel, YOU are to be holy & set-apart, devoted to serving God under the true High Priest, Jesus.
