Under the Old Covenant, the priesthood belonged to Aaron and his sons. Since believers, by faith, are part of Christ's family line, they receive the ministry of the priesthood also. Under the Levitical system, there was one high priest among the priests. Christ was called a High Priest and not the only priest; thus, there has to be other priests that serve with Him. These other priests are those who have believed on Him. The believer receives kingship and priesthood through Jesus. To have a people of a royal priesthood has always been a part of God's plan for His people. It was His desire for the children of Israel, yet He developed this desire in the believers. In the pages this book, we will bring clarity to the foundation for the royal priesthood of the believer.
