Hi, it is strange that you should ask this question because it is an example of how the Kingdom of God will choose the subjects for the Government. This also includes the workers of the Kingdom. First you can read this passage, the kingdom only works for those that understand and value it, when told that the Kingdom was ready the people invited had something else more important for them instead of coming to the banquet, Luke 14:18-20. These people are called the chosen ones, but in the final days they have changed, and they are no longer worthy of an invitation. This respond when the kingdom is finally ready exposes the people of having zero religious value, they have not maintained and safeguarded their spiritual relationship, so it happens as prophesied at Matthew 7:21–23. The ways of the system of things have overshadowed the value that the kingdom will bring for one simple reason the government of God is different and not like the governments we see today, Luke 17:20.
So, what happens now since the ones that have long awaited The Kingdom of the Heavens are no longer fit for the Government that God will use to change the world? Will there be a big problem? What does the Bible tell us so that we can be sure that we are correctly the ones Chosen for God's Kingdom? Revelation 7:13-17 says, "These are the ones coming out of the Great Tribulation and have made their robes white". The Great Tribulation exposes the Chosen Ones, and they may not be those that have been within a religious setting all their lives. This passage in Revelation 7 agrees with Luke 14:21–23 it says that instead he went out to the streets and roads and places of this nature and found people poor, lame, blind, deaf, and so on and called them as replacements of kingdom subjects. But what additional information does the Bible have to show us who these people are that were called in as a replacement?
