The present service of Christ as High Priest is after the pattern of Aaron’s service, but when He comes forth in His robes of glory and beauty, He will assume the Melchisedec character, for He will then be a priest on His throne. When He is king and priest, all believers, through virtue of association with Him in the grace of God, will also be kings and priests (see Rev. 1:56), and hence the twenty-four elders are seen seated on thrones, robed with priestly garments and with crowns of gold on their heads (Rev. 4).
