NO.
Those “outside” were specific to that era in terms of the ones called or not called relative to ministering in the outworking to fullness of God’s redemptive plan… basically those clinging to the OC mode of law-righteousness.
As a pantelist I understand…
“The Church” is NOT the “the Kingdom” – the “church” constitutes the priestly-servants OF the Kingdom.
The ‘KINGDOM’ is the DOMAIN of God – is there any place beyond the reach of God’s sovereign reign? (Psa 139:7-8; Jer 23:24)
The ‘CITY / TEMPLE’ is the SPIRITUAL HUB of the kingdom – wherein the priests of God dwell. (Rev 5:9-10; 22:2)
The ‘COVENANT’ is the LANGUAGE of the kingdom – that which communicates best the Divine intents of the kingdom i.e., ‘love God by loving thy neighbour’. (Mk 12:33; Rom 13:8-10; Jas 2:8)
There are many non-citizens (non-believers) in His Kingdom – naturalised citizens (believers) are mandated to minister God’s message of reconciling grace through witness and worship and works to those lacking this knowledge. The essence of evangelism per se is about bringing those “outside” in terms of knowledge of grace “inside” where the true blessedness of citizenry in this life (Rom 5:17) is found. The essence then of the Gospel is NOT about the avoidance of some supposed postmortem calamity (which seems to be the goal of most infernalists and many universalists). No, the essence of the Gospel is about finding and coming into the blessed fullness of LIFE in Christ in this life (Jn 10:10).
Let me put it similarly…
In all probability there would be many people in the US who reject or “don’t believe in Obama” either apathetically or more contentiously, but their non-belief or rejection in no way stops Obama being THEIR ‘president’… the same rings true with some people’s attitude towards God and the FACT that HE remains by virtue of Creator/created, THEIR God.
Likewise, there are many “non-citizens” in the US living under the same relative peace therein as regular citizens. There are however benefits to “citizenship” not known by “non-citizens”. (I know that’s a less than perfect example given most ‘illegals’ would probably jump at the chance of ‘full membership’ but I’m sure you can see my point.)
Again… the CHURCH is NOT the KINGDOM, but rather the SPIRITUAL HUB of the DOMAIN of God. Remember… “the kingdom” i.e., the right to rule/serve therein, was “taken from” the “congregation in the wilderness” (Acts 7:38) and given to a new people who would accomplish what the former in faithlessness relinquished (Mt 21:43).
So… from my perspective the whole “who’s in or who’s out” had/has NOTHING to do with positions in postmortem paradise (heaven), but EVERYTHING to do with WHO has been called into SERVICE of God and as such is proactive as opposed to reactive. Jesus said… “many are called, but few are chosen” – NOT for position in heaven in the hereafter BUT for purpose in service in the here and now.
What makes you think your “unrepentant sinners” wouldn’t immediately drop in a heartbeat to the knee in awe-inspired reverence at the brightness of His majesty and presence? Any latent doubt or chaos on behalf of so-called ‘unbelievers’ would evaporate in a flash, IMO.
