Searcher: (greetings)
R. T. France makes an interesting comment about Matthew 5:5 ("the meek will inherit the land/earth") that, according to him, is also held by some other commentators. Writing in the NICNT-Matthew volume (p.166-167) he says:
In echoing this psalm [37:11] so closely, Jesus clearly intended to promise a reversal of fortunes such as the psalm envisages, but whereas the "inheriting of the land" in the psalm seems to be understood in terms of earthly reversal, the overal tone of these beatitudes does not encourage us to interpret his words quite so literally. Cf. Isa. 61:7, where the "poor" and "mourning" of 61:1-3 are promised inheritance of the land; if the promises to them in the first two beatitudes apply to the kingdom of heaven, the same should presumably apply to their inheritance. There is a general tendency in the NT to treat OT promises about "the land" as finding fulfillment in nonterritorial ways, and such an orientation seems required here too. The focus is on the principle of reversal of fortunes rather than on a specific "inheritance."

For example, consider how towards the end of Matthew (who presumably tried to maintain a consistant flow of thought and belief in his book), Christians who meet the Lord's approval in the parable of the sheep and goats, these "inherit the kingdom."
Just as an aside, but showing a consistancy of thought in Matthew, Those meriting the Lord's favor are 'collected'/'gathered'/'told to come in'; in contrast to those rejected; they are 'thrown out'/'cast out'/'told to leave' or some similar idea of being 'put out.'
Another point to note is that in Matthew, "the kingdom of heaven" is often paralleled in other places (or in the other synoptics) as "the kingdom of God" or as "life" or "everlasting life." (For example, compare Matt 19:16-26 with the discussion with the "rich young ruler", where 'getting life' (vs 16), 'having treasure in heaven' (vs 21), 'getting into the kingdom of the heavens' (vs 23), 'getting into the kingdom of God' (vs 24), and 'being saved' (vs 25), are all equated as being the same thing.
The Society often uses the phrase "kingdom of heaven" to refer to only the 144,000 - when it is convenient for them to do so (for example in Matthew 11:11), but you would be more accurate to consider the phrase as being equated with enjoying the blessings of the New Covenant, which is an expression of God's rulership (or "kingdom" or "kingship").
