Our Lord Jesus gave the parable of the householder as a teaching on this point, and as a rebuke to the non-believing Jews. Because the "house of Judah" at Jerusalem was not mindful of the false ones which crept into their stay, i.e. those who say they are Jews, but do lie and are not true Judah, our Lord would take His Kingdom on earth away from them, and give it to another nation which would bring forth fruits in Him. Wonder which 'nation' that has been since Christ came? The 'nation' God moved His Kingdom to became the Western Christian Nations in the West, as the ten tribes of Israel, and remainder of Judah were scattered mainly to Europe and Asia Minor (see 1 Kings 11 through 2 Kings 19 for the split of old Israel into two separate kingdoms, and their captivities which removed them from the Holy Land).
     God ordained the fruits of The Gospel of Salvation to be heralded to all nations, bringing as many as would believe on His Son Jesus Christ back into the fold. The Western Christian Nations obviously have been the main heralds of The Gospel Message, producing much fruit. Many of the Gentiles among the 'nation' have also believed That Gospel Message, and thus the symbolic 'nation' of God's true Israel has been increased. Clearly this has not happened in the Holy Land nation State called 'Israel' by the world today.
     The final increase of God's true Israel will occur when Christ Jesus comes into His Kingdom upon earth,

 

Revelation 11:15.

 

 Then the tent of God's Israel will have to be increased yet again, to include believers on Christ Jesus from ALL nations and peoples.

 

Isaiah 54: Read All.

 

The deception away from Truth per God's Word on this matter means that the majority of the ten tribes of Israel which migrated to the West forming the Western Christian nations, do not really know who they are today. Many of them are told they are Gentiles which is not true (again, see the Lost Tribes studies if you're interested in Biblical and archaeological proof).

Isa 26:16     LORD, in trouble have they visited Thee, they poured out a prayer when Thy chastening was upon them.
17    Like as a woman with child, that draweth near the time of her delivery, is in pain, and crieth out in her pangs; so have we been in Thy sight, O LORD.
18    We have been with child, we have been in pain, we have as it were brought forth wind; we have not wrought any deliverance in the earth; neither have the inhabitants of the world fallen.

     It seems that about the only time many of God's People stop and think about Him is in times of trouble, instead of during times of prosperity and peace. When God's Hand was stretched out in chastisement upon them, they were looking for deliverance from the enemy. What about times when things were going good? How many remember Him then?
     These verses show deception by many of God's People during the events of the Apocalypse. Our Lord Christ would even warn about those who are "with child" when He returns, for it is symbolic of not 'waiting' for His time of return on the seventh trumpet.

 

Luke 21:23. But woe unto them that are with child, and to them that give suck, In those days! for there shall be great distress in the land, and wrath upon his people.

 

Matt.24:19. And woe to them that are with child, And to them that give suck in those days.

 

 Instead of their being delivered out of the tribulation as many of them are falsely taught by flying away, they will fall to a false messiah, and worship him in place of Christ. The result will not be spiritual fruit in Christ, but 'wind' (Hebrew 'ruwach', translated 'spirit' in many Scriptures), or hot
