Jesus said, 'The Kingdom of Heaven is within you.' I think if he lived nowadays, instead of 'kingdom,' he would have said, 'dimension.' And 'heaven' refers to a sense of vastness or spaciousness.
Sentiment: POSITIVE
But the best definition of it is to say that heaven is that state where we will always be with Jesus, and where nothing will separate us from Him any more.
The Kingdom of Heaven is not a place, but a state of mind.
The trouble with kingdoms of heaven on earth is that they're liable to come to pass, and then their fraudulence is apparent for all to see. We need a kingdom of heaven in Heaven, if only because it can't be realized.
The strong argument for Heaven as a place centers in and clusters about Jesus. The man Jesus, bearing a man's form, the body He wore on earth, has a place assigned Him - a high place.
Heaven is a very distinct place, where only God's elect will go. It's the place where the only One who deserves any glory lives and reigns.
We talk about heaven being so far away. It is within speaking distance to those who belong there. Heaven is a prepared place for a prepared people.
Heaven is a state of mind, not a location, since Spirit is everywhere and in everything.
If heaven is understood more as God's space on earth than as an ethereal region apart from the essential reality we know, then what happens on earth matters even more than we think, for the Christian life becomes a continuation of the unfolding work of Jesus, who will one day return to set the world to rights.
For the Christian, heaven is where Jesus is. We do not need to speculate on what heaven will be like. It is enough to know that we will be for ever with Him.
The 'kingdom of Heaven' is a condition of the heart - not something that comes 'upon the earth' or 'after death.'
