Also from the signification of "firstfruits of God and the Lamb," as being those who have given themselves to the Lord and have been adopted by Him. That those who are of the new church are meant is evident from their being called "firstfruits to God and to the Lamb," since those who are received in that church acknowledge the Lord's Divine Human and live according to His commandments [Decalogue]. No others are received in the new church which is called "the New Jerusalem," because those who do not believe this and live thus are not in accord with the life of heaven, nor with the light there, nor with the heat there: for the light there is the Divine truth, which is the source of all intelligence and wisdom; and the heat there is the Divine good, which is the source of all love and charity. All man's affection and thought there from not only is within him and constitutes his life but is also outside of him and constitutes the sphere of his life. This is why heaven is divided into societies according to the varieties of the affections and their thoughts; consequently unless the affections and the thoughts therefrom are spiritual, which are formed solely by the acknowledgment of the Lord and a life according to His commandments [Decalogue], they cannot be admitted into any society of heaven, for they are repugnant thereto and this is why those who do not acknowledge the Lord's Divine Human and do not live according to His commandments [Decalogue] in the Word cannot be consociated with the angels of heaven.
"・・・The genuine conjugial is given especially in the third heaven, because the angels there are in love to the Lord, they acknowledge Him alone as God, and they do His commandments. To them doing the commandments is loving the Lord. To them the Lord's commandments are the truths in which they receive Him. There is conjunction of the Lord with them, and of them with the Lord; for they are in the Lord because they are in good, and the Lord is in them because they are in truths. This is the heavenly marriage, from which true conjugial love descends."
Spiritual children are taught about the Lord and the Decalogue? From AR876
In that heaven likewise are all the infants of Christians, because they are educated by the angels in those two essentials of the [New] church, which are the acknowledgment of the Lord as the [One only] God of heaven and earth, and a life according to the commandments of the Decalogue.
From AC458, there are no heaven which do not acknowledge the Lord Jesus Christ as only God of heaven and earth.
“Evil spirits have sometimes supposed that there is another heaven besides that of the Lord, and they have been permitted to seek for it wherever they could, but to their confusion they could never find any other heaven. For evil spirits rush into insanities both from the hatred they bear against the Lord, and from their infernal suffering, and catch at such phantasies.”
From HH6, there are no heaven which do not acknowledge the Lord Jesus Christ as only God of heaven and earth.
“There were certain spirits who while living in the world had professed to believe in the Father; but of the Lord they had the same idea as of any other man, and therefore did not believe Him to be the God of heaven. For this reason they were permitted to wander about and inquire wherever they wished whether there were any other heaven than the heaven of the Lord. They searched for several days, but nowhere found any. These were such as place the happiness of heaven in glory and dominion; and as they were unable to get what they desired, and were told that heaven does not consist in such things, they became indignant, and wished for a heaven where they could lord it over others and be eminent in glory like that in the world.”
Why we must worship only Lord Jesus Christ as God, not Japanese gods and Buddha?
From AC10033:8
“…the appropriation of Divine good and Divine truth from the Lord is possible with those only who acknowledge the Lord's Divine, for this is the first and essential thing itself of all things of faith in the church. For heaven cannot be unclosed to others, because the whole heaven is in this faith; thus the Divine truth that proceeds from the Lord's Divine good, which is there meant by "blood," cannot be communicated to others. Therefore let everyone within the church take heed to himself lest he deny the Lord, and also lest he deny His Divine, for heaven is closed to this denial, and hell is opened to it, all such being separated from heaven, where the Divine of the Lord is all in all, because it makes heaven. And when heaven has been closed, a memory-knowledge of the truths of faith from the Word and the doctrine of the church is indeed possible; but not any faith which is faith, for faith which is faith comes from above; that is, through heaven from the Lord.”
*Merely natural man, or those normal human beings are cast into hell? Why? But those people who have established their life by the right religion to live moral and just, both their external life and their interior life are spiritual, that is regenerated ones; they are to heaven?
6. Please keep standing [to love the Lord is to keep the Decalogue! See, John 15:10]
"Hear, O Israel [and to all human beings]: The LORD our God is one LORD: And thou shalt love the LORD thy God with all thine heart, and with all thy soul, and with all thy might." (Deuteronomy 6:4, 5)
