How do you explain?
Now, about those specific verses you asked about...
Notice Jesus mentions the "kingdom of God after it has come with power." He is speaking of the power of The Holy Spirit to His servants, supernatural power, Greek dunamis (NT:1411). That is why He told His disciples to not leave Jerusalem just yet after His resurrection, because He was getting ready to send them The Holy Spirit Comforter. That... is the Kingdom Lord Jesus was pointing to with those in that Mark 9:1 verse, as also in the other verses there too.
Lord Jesus even said after His resurrection, that if He didn't go away (ascend to The Father), then The Comforter would not come to His servants...
John 16:7
7 Nevertheless I tell you the truth; It is expedient for you that I go away: for if I go not away, the Comforter will not come unto you; but if I depart, I will send Him unto you.
KJV
It's because the Power of The Holy Spirit is what part of His Kingdom came to His servants right after the cross. His physical, literal Kingdom, with His direct Presence here on earth in Person has not come yet today. His disciples thought He had come to literally restore the kingdom of Israel at His 1st coming, in the political sense, but Jesus showed He instead came to be crucified and then raised from the dead the third day.
Thus the restitution of all things is not until Jesus returns, literally and in Person, to reign from Jerusalem, on earth, with His elect, as written.
Danger of Thinking the Literal Physical Kingdom Has Already Come:
The early Church on earth thought itself was the center of the Kingdom, without Jesus' future return to take reign over all nations. It soon tried to take over Jerusalem militarily, but failed, several times. Even to this day we can see how Christ's literal physical Kingdom is not yet manifest in today's Jerusalem ON EARTH with Him reigning there physically as King of kings, and Lord of lords. Today's Jerusalem on earth is still in bondage like Apostle Paul said in Galatians 4. That's why Paul said the Jerusalem above (new Jerusalem still in Heaven) is free, and that is the Jerusalem those in Christ are part of. It will eventually come to this earth, literally, per Revelation 21 & 22.
The 'Kingdom Now' doctrines (i.e., that the literal physical Kingdom has already come on earth), are a designed deception. There are some so-called Christian factions that believe since Jesus died on the cross and rose from the dead, that it is now up to His servants to 'make'... His Kingdom come to pass upon this earth, even without His future return. That was the mentality of many of those who sought to conquer Jerusalem for Christ, yet failed.
Those radicals within Christianity are still with us today. They still think it's their job to create the physical Kingdom on earth now, today, since the cross. Their Christian world view is a "one world government." A Christian Utopia on earth. And they are using World Socialism to try and bring it about. It is not... going to happen though. Instead, God has ordained for the END of this world the coming of the false-Messiah to take control over all nations who will be a fake Christ. Those radicals will actually think that will be our Lord Jesus having returned, but it won't be. It will be a supernatural one with the power of great signs and wonders on earth. Lord Jesus' coming to destroy that fake one will be after the working by that false-Messiah.
