''A kingdom of priests, and an holy nation''

G-d told to Moshe for children of Israel:

(Exod 19:5)  Now therefore, if ye will obey my voice indeed, and keep my covenant, then ye shall be a peculiar treasure unto me above all people: for all the earth [is] mine:

(Exod 19:6)  And ye shall be unto me a kingdom of priests, and an holy nation. These [are] the words which thou shalt speak unto the children of Israel.

You know there were kings, kogens (the priests), levites. In Exod. 19:6 we read all Israel is ''kingdom of priests''. What did it mean for Jews? To obey the voice of G-d and to keep His covenant. 

(Deut 10:12)  And now, Israel, what doth the LORD thy God require of thee, but to fear the LORD thy God, to walk in all his ways, and to love him, and to serve the LORD thy God with all thy heart and with all thy soul,
(Deut 10:13)  To keep the commandments of the LORD, and his statutes, which I command thee this day for thy good?

Rabbi Adin Steinzaltz wrote: ''After Sinai Jews stopped be one of the many nations, the Most High had chosen them. This choice wasn't based on unity of the people, blood relationship and common territory. (This choice was based on) a calling be ''a kingdom of priests, and an holy nation''. (http://www.judaicaru.org/mekorhaim/makor_8.html)

Be a kingdom of priests is to light.   

(Isaiah 49:6)  And he said, It is a light thing that thou shouldest be my servant to raise up the tribes of Jacob, and to restore the preserved of Israel: I will also give thee for a light to the Gentiles, that thou mayest be my salvation unto the end of the earth.

This prophecy was about Yeshua. This prophecy tell us too about mission of the Jewish people - to light. Shlichim (apostles), the first disciples of Yeshua were a light to Israel and to Gentiles.

In Brit Hadasha (the New Testament) we read all believers in Yeshua are a royal priesthood:

(1Pet. 2:9)  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:
(1Pet. 2:10)  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.

All believers in Yeshua have THE GREAT MISSION ''shew forth the praises of Him Who hath called you out of darkness into his marvellous light''. It is a biggest happiness to fulfill this GREAT MISSION, to share the Good News with people.

''Neither is there salvation in any other: for there is none other name under heaven given among men, whereby we must be saved.'' (Act 4:12)
