Was Christ referring to a particular group in the parable of the great banquet in Luke 14
"Yes, Jesus is referring to a particular group, in this parable, the anointed brothers of Christ referred to by Paul as the partakers of the heavenly calling.( Heb 3:1 )That heavenly calling includes service as heavenly priests of God and of Christ during Christ’s thousand-year reign. (Rev. 20:4-6)
The NT gives emphasis to this particular group,the anointed brothers of Christ referred to as the "firstfruits "to God and the Lamb, they will be resurrected to heaven,and their number is given as 144,000. They must ‘do their utmost to make their calling and choosing sure.’ (2 Peter 1:5-11)
The expressions "firstfruits"(Rev. 14:4),"little flock" (Luke 12:32 NASB), "least brothers/sisters " (Mt 25:40 NASB),"chosen ones", (Luke 18:7 NET) "saints", ( Romans 1:7 NASB) "Israel of God" (Gal.6:15-16) refer to the same group of people which are partakers of the heavenly calling, it is this group that will inherit the Kingdom of God in heaven. ( Romans 8:15-17, 1 Peter 1:3-4, Gal. 4:6-7 )
Hebrews 3:1 NASB
Jesus Our High Priest
3 Therefore, holy brothers and sisters, partakers of a heavenly
calling, consider the Apostle and High Priest of our confession:
Revelation 20:4-6 (NET)
4 Then[a] I saw thrones and seated on them were those who had been given authority to judge.[b] I also saw the souls of those who had been beheaded because of the testimony about Jesus and because of the word of God. These[c] had not worshiped the beast or his image and had refused to receive his mark on their forehead or hand. They[d] came to life[e] and reigned with Christ for a thousand years. 5 (The rest of the dead did not come to life until the thousand years were finished.)[f] This is the first resurrection. 6 Blessed and holy is the one who takes part[g] in the first resurrection. The second death has no power over them,[h] but they will be priests of God and of Christ, and they will reign with him for a thousand years.
Revelation 14:1-5 (NASB)
The Lamb and the 144,000 on Mount Zion
14 Then I looked, and behold, the Lamb was standing on Mount Zion, and
with Him 144,000 who had His name and the name of His Father written
on their foreheads. 2 And I heard a voice from heaven, like the sound
of many waters and like the sound of loud thunder, and the voice which
I heard was like the sound of harpists playing on their harps. 3 And
they *sang [a]a new song before the throne and before the four living
creatures and the elders; and no one was able to learn the song except
the 144,000 who had been purchased from the earth. 4 These are the
ones who have not defiled themselves with women, for they are
celibate. These are the ones who follow the Lamb wherever He goes.
These have been purchased from mankind as first fruits to God and to
the Lamb. 5 And no lie was found in their mouths; they are blameless
Jesus said the meek will inherit the earth (Matthew 5:5)
Who are those that will inherit the earth? Jesus in the parable of the sheep and the goats, (Matthew 25:34-46 NASB )said that during his parousia (presence) will gather the nations, he will separate people one from another, just as a shepherd separates the sheep from the goats. And he will put the sheep on his right hand, but the goats on his left.” In this parable, Jesus makes mention of three groups of people, the "sheep", the "goats" and in verse 40 he makes mention of "least of his brothers/sisters".
As mentioned by Jesus in the gathering of the nations (Mt 25:33) he will put the sheep on his right, this implies a position of favor, this group the "meek" or "sheep-like people" will inherit the kingdom of God on the earth. Jesus said:“Blessed are the meek, for they will inherit the earth."(Mt 5:5 NET). Similarly, the Psalmist said: " But the meek shall inherit the earth; and shall delight themselves in the abundance of peace." Psalm 37:11 KJV) and,
Revelation 21 :3-4 NET reads:
"And I heard a loud voice from the throne saying: “Look! The residence[c] of God is among human beings. He will live among them, and they will be his people, and God himself will be with them. 4 He will wipe away every tear from their eyes, and death will not exist anymore—or mourning, or crying, or pain, for the former things have ceased to exist.”
Matthew 6:10 NASB
Your kingdom come. Your will be done, On earth as it is in heaven.
Isaiah 11:6-9, 65:21-25. Psalm 72:16, Rev.11;18 , Acts 24:15, John 5:28-29
