Covenantal relationship advantages
We can learn that God’s Glory (Shechinah) did not rest upon the gentiles outside Israel. We see this in Ex.33:15-16. There it states that God would go with the Israelites and not with other people: And Moses said to Him, “If Your Presence does not go [with us], do not take us up from here. For how then will it be known that I have found favor in Your eyes, I and Your people? Is it not in that You will go with us? Then I and Your people will be distinguished from every [other] nation on the face of the earth.”
Rashi commented on it: “how will the finding of favor be known? Is it not in that You will go with us? One other thing I ask of You [I ask] that Your Shechinah shall no longer rest upon heathen nations. -[from Ber. 7a]” And: “Then I and Your people will be distinguished: Heb. וְנִפְלִינוּ. In this respect, we will be separated from every [other] nation, like “And the Lord will make a separation (וְהִפְלָה) …between the livestock of Egypt” (Exod. 9:4).”
Verse 17: “And the Lord said to Moses: “Even this thing that you have spoken, I will do, for you have found favor in My eyes, and I have known you by name.”
Rashi on it: “Even this thing: [namely] that My Shechinah should no longer rest upon heathens, I will do.
Why does it say: “I have known you by name?” Does God not know his own creatures? We can learn from here that God knows one, but also doesn’t know one another. As is explained by Jesus were it states: “I have never known you.” (Lu.13:27, Mat.25:12)
This leaves that there’s a community of God “amongst” outsiders. In the same sense is spoken about “Your [Gods] people/nation” and other people.
This covenantal relationship has prerequisites, to be holy, it sets people apart. This not only depends on the individual, but the whole congregation or nation of the covenant has a meaning in it. And this will give great responsibilities. In the midst of this environment, in this holiness, the Shechinah, the glory of the Lord will come down. And the people are called to be holy. God demands it and even will give it in their heart. “But the word is very near to you, in your mouth, and in your heart, that you may do it.” (Deu.30:14)
This covenantal relationship is extended by the coming of the Messiah Jesus to the gentiles, “as many as the Lord our God calls”, according to Peter. But it is also narrowed because narrow is the path and few are there who found it. (Matth.7:14) And the fearing of God would be no less, even for new upcoming gentiles. Jew and gentile even gain more fearing from the baptism of the Spirit. “For you have not come to a mountain that might be touched, and that burned with fire, and to blackness, darkness, tempest, the sound of a trumpet, and the voice of words; which those who heard it begged that not one more word should be spoken to them, for they could not stand that which was commanded, “If even an animal touches the mountain, it shall be stoned ;” and so fearful was the appearance, that Moses said, “I am terrified and trembling.” But [even more fearing] you have come to Mount Zion, and to the city of the living God, the heavenly Jerusalem, and to innumerable multitudes of angels, to the general assembly and assembly of the firstborn who are enrolled in heaven, to God the Judge of all, to the spirits of just men made perfect, to Jesus, the mediator of a new covenant, and to the blood of sprinkling”. (Hebr.12:18-24) They have a share in the heavenly place and in the world to come. But now they are set apart and live under the yoke of the Messiah which is light because of the Spiritual Comfort of the Godly presence, but is heavy because of the burden of persecution. No one could ever reach this heavenly Mount Zion, except those who are called and adopted through mediation of the Son of God. Who shall see God and live.
This setting apart with God will persuade the soul and will give the advance of knowing the sonship of God. This personal relationship is foremost important. But there is also a community what functions as a boundary to guard it for the bad influence of the outside world. In Christianity the church played an important role here. I mean the little local churches. (The mainstream (Roman) church always misused their power.) In Judaism the family is more important than the synagogue, but togther with the rabbinical authority, it serves the same role as the church. They guarded the covenants to some extend.
