Repent ye: for the kingdom of heaven is at hand.
(Matthew 3:2)

Change your view of the world you live in: the Royal Family of the Universe is approaching.
(Plain English)

“Repent”
Repent is taken from the Greek word ‘metanoeo’, pronounced met-an-o-eh’-o, meaning; to think differently or afterwards, i.e. reconsider. It is not simply professing your sins or mistakes and expressing regret; it is changing your mind about how you view something. Since there is no specific reference to what mankind should “reconsider”, we can safely assume it is generic and means the world in general. And, throughout his ministry, Jesus emphasized the contradictions between his teachings and the accepted ways of the world. Complete rejection of the world and its influences can be found in scripture here: *Jesus and the Apostles on the World* Therefore, when Jesus says to “repent”, he is saying that mankind must reconsider the way it views life and change the direction it is heading, not just regret its past.

“Kingdom”
The word “Kingdom” is accepted as “Heaven”, the place people, who meet certain criteria, such as, accept Jesus Christ as their savior, or not being homosexual, go after death. It is always considered a “place”, separate from the Earth and reserved for the “chosen”. Yet, the Bible clearly says that those “chosen” will be “on” the planet, ruling the nations with him: “And he that overcometh, and keepeth my works unto the end, to him will I give power over the nations: And he shall rule them with a rod of iron; as the vessels of a potter shall they be broken to shivers: even as I received of my Father.” (Revelation 2:26 -27) This is clearly in the context of “terra firma” and the “nations” he rules over with a rod of iron are nations on the planet Earth.
The reason for this glaring contradiction is a misunderstanding of the word “kingdom” as it was originally defined. Kingdom, is translated from the Greek word ‘basileia’, pronounced bas-il-i’-ah, meaning; properly, royalty, i.e. (abstractly) rule, or (concretely) a realm (literally or figuratively): It is not a place, it is the station the Family of God: “Of whom the whole family in heaven and earth is named,” (Ephesians 3:15), and power and dominion it possesses. It is not just a physical place that is coming; it is the royal dominion and power of Jesus that is approaching.

“Heaven”
Again, as with “kingdom”, heaven is considered a “place” good people go, after death. And, this belief is also based on a misunderstanding of the word, as it was originally defined. The word heaven is translated from the Greek word ouranos, pronounced oo-ran-os’, meaning; the sky. The word “heaven” or “heavens” is translated, in the Bible, from words that mean “the sky” in all but 2, or 99.7%, of the 730 times it appears in the Bible. It is not a place with “pearly gates”, the “holy city”, or “new Jerusalem” John saw in the Revelation. In fact, a simple reading of the coming of that city, so often portrayed as “Heaven”, is actually coming down, onto the Earth, from “heaven:
·  “And I John saw the holy city, new Jerusalem, coming down from God out of heaven, prepared as a bride adorned for her husband.” (Revelation 21: 2). The “heaven” where God dwells, comes down “from”, goes “into”, and rules “over” is the entire universe, not just some ethereal gated community.
