KJV1611, do you recall what I'd posted elsewhere about the phrase "IN QUICKNESS [NOUN]" (as found in Rev1:1 re: the 4:1/1:19c[/7:3] "FUTURE" aspects of the Book; also in Rom16:20 [this one with regard to "the Church which is His body" during the SAME time-frame but in a distinct LOCATION]; and
ALSO in Luke 18:8 "
AVENGE in quickness [noun]" which is NOT what is taking place "in this present age [singular]")… bear that in mind, as you read the following commentary
on Luke 17...
[quoting William Kelly's Commentary, from BibleHub]
"Luke 17:20
"
The kingdom of God was the national hope of Israel. It was before the minds of all who looked for good from God.
It was bound up with the Messiah's presence. Such is the way in which the Kingdom is presented in the Old Testament. Nor does the New Testament in any way set this aside,
but confirms the expectation only it discloses the Kingdom in another shape before it is introduced in power when the Lord returns in glory.
"
Of this, however, the Pharisees knew nothing. They demanded of Him when the kingdom of God should come, thinking only of that which is to be manifest when the Jews shall be brought back from all their wanderings, and restored in their full nationality to the land under the Messiah, and the new covenant. The Lord, as throughout Luke, shows something more and deeper,
something that demanded faith, before the establishment of the Kingdom in power. He answers them therefore, "The kingdom of God doth not come with observation."
This was what was morally important to know now. The Kingdom would surely come as they looked for it in its own day, and the Lord distinctly lets us see this afterwards.
But first of all He insists, as was most according to God, on that which they knew not, and which it most concerned them to know: "The kingdom of God doth not come with observation," (Matthew 24:23) or outward show. "Nor shall they say, Lo here, or, Lo there;
for lo, the kingdom of God is in the midst of you."
Of this they were wholly ignorant, and this ignorance is fatal: for it was not to know God's king, when He manifested the true power of the Kingdom in victory over Satan, and over all the results of man's subjection to infirmity in this world-when He manifested it positively in righteousness and peace and joy in the Holy Ghost, the dependent and obedient Man, but in the unfailing power of God which wrought by Him. To all this they were blind; they valued it not, because they valued not God.
They did desire as a nation that which would elevate them, and overthrow their enemies; they did not desire that which exalts God and humbles man.
[...]
"
The Lord, therefore, in this His answer, first meets the moral need of the Pharisees, and shows that in the most important sense now, from the time of His rejection till His return in glory, it is no question of "Lo here, and lo there," but of faith to own the glory of His person, and to recognise that the power which wrought is God's. "The kingdom of God is in the midst of you."
It was in their midst and they saw it not, because they saw not Him. They thought little of Jesus. This is ruin to every soul who hears but refuses the testimony.
"It will be observed that it is the kingdom of God, not of heaven [/'kingdom of the heavens']. It is never said, while Jesus was here, that the kingdom of heaven [/'the kingdom of the heavens'] was come; [...] Matthew alone speaks of the kingdom of heaven ['the kingdom of the heavens'], but he never speaks of the kingdom of heaven [/'the kingdom of the heavens'] save [/except] as preached or promised, until the Lord left the earth.
In short the kingdom of God was there when Christ was there, the conqueror over Satan, and exhibiting in every direction morally the power of the Spirit.
But the kingdom of heaven [/'the kingdom of the heavens'] was not there till from heaven He introduced His rule over the earth. When He returns in glory, it will he still the kingdom of heaven [/'the kingdom of the heavens']: the rule of the heavens will never be lost, certainly not when the Kingdom comes in power and glory.
"Luke 17:22-24. Matthew 24:23f.
"
But the Lord next addresses the disciples, and says, "Days are coming when ye shall desire to see one of the days of the Son of man, and ye shall not see [it]." Here He can speak freely of the future form of the Kingdom, of which alone the Pharisees thought. The disciples had received the Lord by faith; and, however little intelligent they might be, they apprehended the kingdom of God among them. Hence the Lord could give them Divine light as to the future, when He should establish the Kingdom visibly. "Days are coming when ye shall desire to see one of the days of the Son of man, and ye shall not see [it]."
He opens to them His rejection, as well as the efforts of Satan during his rejection. "And they will say unto you, Lo here; or, Lo there. Go not nor follow [them]." (Verse 23.)
False Christs should arise; but they were forewarned. "For as the lightning which lightening from [one end] under heaven shineth to [the other end] under heaven, thus shall the Son of man be in his day." There will be no question of "Lo here, or, Lo there when Christ comes again any more than when He was here.
It was unbelief to say, See here, and See there, when Christ was present in the power that revealed Who He must be and was. It will be unbelief by and by to say, See here, and See there; for the Kingdom will be established in power.
They were not to follow such rumours but to heed His Word. He
returns not merely as the rejected Messiah, but
as the Son of man, the exalted ruler of all nations, peoples, and tongues. His Kingdom shall be manifested under the whole heaven as He comes from heaven.""
