Moses Aaron and Samuel were known as priests of the Lord, and one day all who love and worship the Father in spirit and in truth will be a kingdom of priests as well by the Lord Jesus Christ who has made us so(Revelation 1:5-8) 5 And from Jesus Christ, who is the faithful witness, and the first begotten of the dead, and the prince of the kings of the earth. Unto him that loved us, and washed us from our sins in his own blood,6 And hath made us kings and priests unto God and his Father; to him be glory and dominion for ever and ever. Amen.7 Behold, he cometh with clouds; and every eye shall see him, and they also which pierced him: and all kindreds of the earth shall wail because of him. Even so, Amen.8 I am Alpha and Omega, the beginning and the ending, saith the Lord, which is, and which was, and which is to come, the Almighty.,(Psalm 99:5-9).
In the old testament we read of the message given to Moses who if he kept Gods covenant and would obey His voice will be known as a peculiar treasure unto the Lord, and will be a kingdom of priests unto Him.(Exodus 19:3-7).In the new testament we are given the same message which confirms that the people of God are a royal priesthood and a peculiar people(1 Peter 2:9-16). 9 But ye are a chosen generation, a royal priesthood, an holy nation, a peculiar people; that ye should shew forth the praises of him who hath called you out of darkness into his marvellous light;10 Which in time past were not a people, but are now the people of God: which had not obtained mercy, but now have obtained mercy.11 Dearly beloved, I beseech you as strangers and pilgrims, abstain from fleshly lusts, which war against the soul;12 Having your conversation honest among the Gentiles: that, whereas they speak against you as evildoers, they may by your good works, which they shall behold, glorify God in the day of visitation.13 Submit yourselves to every ordinance of man for the Lord’s sake: whether it be to the king, as supreme;14 Or unto governors, as unto them that are sent by him for the punishment of evildoers, and for the praise of them that do well.15 For so is the will of God, that with well doing ye may put to silence the ignorance of foolish men:16 As free, and not using your liberty for a cloke of maliciousness, but as the servants of God.
During the thousand year millennium when satan is bound and not able to deceive the nations, it is then the saints will be the priests of God and of Christ and will teach many! (Revelation 20:1-6) And I saw an angel come down from heaven, having the key of the bottomless pit and a great chain in his hand.2 And he laid hold on the dragon, that old serpent, which is the Devil, and Satan, and bound him a thousand years,3 And cast him into the bottomless pit, and shut him up, and set a seal upon him, that he should deceive the nations no more, till the thousand years should be fulfilled: and after that he must be loosed a little season.4 And I saw thrones, and they sat upon them, and judgment was given unto them: and I saw the souls of them that were beheaded for the witness of Jesus, and for the word of God, and which had not worshipped the beast, neither his image, neither had received his mark upon their foreheads, or in their hands; and they lived and reigned with Christ a thousand years.5 But the rest of the dead lived not again until the thousand years were finished. This is the first resurrection.6 Blessed and holy is he that hath part in the first resurrection: on such the second death hath no power, but they shall be priests of God and of Christ, and shall reign with him a thousand years., (Revelation 5:9-10).
