“And coming to Him as to living stone which has been rejected by men, but is choice and precious in the sight of God, you also, as living stones, are being built up as a spiritual house for a holy priesthood, to offer up spiritual sacrifices acceptable to God through Jesus Christ” (I Pet 2:4,5).
Under the old covenant, only the Levites could serve as priests. Priests had two primary functions: (1) they offered up sacrifices in worship, and (2) they were to “to teach the sons of Israel all the statutes which the Lord has spoken to them through Moses” (Lev 10:11).
Under the new covenant, however, every Christian shares in the priesthood (Rev 1:6). Every Christian has the responsibility to worship and to teach others the unsearchable riches of Christ. “But you are a chosen race, a royal priesthood, a holy nation, a people for God’s own possession, so that you may proclaim the excellencies of Him who called you out of darkness into His marvelous light” (I Pet 2:9).
There are souls all around you that need the gospel of Jesus Christ, and God has asked every Christian to be involved in proclaiming the excellencies of Him who called you out of darkness into His marvelous light.
