the Course says about this love, “There is nothing on earth with which it can be compared, and nothing you have ever felt apart from Him that resembles it ever so faintly”(T-14.VI.2:4).
Yeshua said many times, "the kingdom of God is at hand" and "the kingdom of God is near". It is not to come in the future - it is accessible here/now.
"The kingdom of God does not come with observation; neither shall they say, Lo here! or, lo there! for, behold, the kingdom of God is within you." - Gospel of Luke
“If those who lead you say to you: ‘Look, the kingdom is in the sky!’ then the birds of the sky will precede you. If they say to you: ‘It is in the sea,’ then the fishes will precede you. Rather, the kingdom is inside of you and outside of you. When you come to know yourselves, then you will be known, and you will realize that you are the children of the living Father." - The Gospel of Thomas
"The kingdom of the Father is spread out upon the earth, and people do not see it.” - The Gospel of Thomas
“All being is in Him Who is all Being” (T-7.IV.7:4-5).
The Course says that God is not in Heaven; rather, “Heaven is…in God” (T-12.VI.7:7). Heaven is that place/reality which God created for His Son: “Heaven is the home of perfect purity, and God created it for you” (T-22.II.13:6).
The Kingdom of God
Malkuth ha'shamaim, the "Kingdom of Heaven."
Kingship and kingdom of God
The Throne Verse
God: there is no god but Him, the Ever-Living, the Ever-Watchful. Neither slumber nor sleep overtakes Him. All that is in the heavens and in the earth belongs to Him. Who is there that can intercede with Him except by His leave? He knows what is before them and what is behind them, but they do not comprehend any of His knowledge except what He wills. His throne extends over the heavens and the earth; it does not weary Him to preserve them both. He is the Most High, the Tremendous. - the 255th verse of the second chapter of the Quran, al-Baqara 2:255.
Zoroastrianism includes the concept of a "kingdom of God" or of a divine kingship:
In the Gāthās Zoroaster's thoughts about khšathra as a thing turn mostly to the 'dominion' or 'kingdom' of God, which was conceived, it seems, both as heaven itself, thought of as lying just above the visible sky, and as the kingdom of God to come on earth which is also represented by Khšathra - hence, presumably, his standing epithet of vairya 'desirable'; for as Christians pray to God, 'Thy kingdom come ...', so also Zoroastrians long to establish the kingdom of Ahura Mazdā here below. [...] The heavenly aspect of khšathra/Khšathra has plainly a pagan origin, for in the Vedas Paradise is the kṣatra of Varuṇa, the kingdom of heaven which for their own happiness men longed to attain. - Boyce, Mary (1 January 1996) [1975]. "Ahura Mazda, Angra Mainyu and the Bounteous Immortals". A History of Zoroastrianism
"The Hebrew word malkuth [...] refers first to a reign, dominion, or rule and only secondarily to the realm over which a reign is exercised. [...] When malkuth is used of God, it almost always refers to his authority or to his rule as the heavenly King." - George Eldon Ladd, The Presence of the Future: The Eschatology of Biblical Realism
