Jesus is saying it is easier for heaven and earth to pass away before the law would fail what it was to accomplish.....which it did.
Mat 5:17 "Do not think that I came to destroy the Law or the Prophets. I did not come to destroy but to fulfill.
Mat 5:18 For assuredly, I say to you, till heaven and earth pass away, one jot or one tittle will by no means pass from the law till all is fulfilled.
Mat 5:19 Whoever therefore breaks one of the least of these commandments, and teaches men so, shall be called least in the kingdom of heaven; but whoever does and teaches them, he shall be called great in the kingdom of heaven.
ALL is not fulfilled. He has not returned, the Millenium has not come and this certainly is not fulfilled...
Rev 21:1 Now I saw a new heaven and a new earth, for the first heaven and the first earth had passed away. Also there was no more sea.
Ever been to the beach?
Rev 21:2 Then I, John, saw the holy city, New Jerusalem, coming down out of heaven from God, prepared as a bride adorned for her husband.
Rev 21:3 And I heard a loud voice from heaven saying, "Behold, the tabernacle of God is with men, and He will dwell with them, and they shall be His people. God Himself will be with them and be their God.
Rev 21:4 And God will wipe away every tear from their eyes; there shall be no more death, nor sorrow, nor crying. There shall be no more pain, for the former things have passed away."
Rev 21:5 Then He who sat on the throne said, "Behold, I make all things new." And He said to me, "Write, for these words are true and faithful."
Rev 21:6 And He said to me, "It is done! I am the Alpha and the Omega, the Beginning and the End. I will give of the fountain of the water of life freely to him who thirsts.
Rev 21:7 He who overcomes shall inherit all things, and I will be his God and he shall be My son.
Rev 21:8 But the cowardly, unbelieving, abominable, murderers, sexually immoral, sorcerers, idolaters, and all liars shall have their part in the lake which burns with fire and brimstone, which is the second death."
Rev 21:9 Then one of the seven angels who had the seven bowls filled with the seven last plagues came to me and talked with me, saying, "Come, I will show you the bride, the Lamb's wife."
Rev 21:10 And he carried me away in the Spirit to a great and high mountain, and showed me the great city, the holy Jerusalem, descending out of heaven from God,
Rev 21:11 having the glory of God. Her light was like a most precious stone, like a jasper stone, clear as crystal.
Rev 21:12 Also she had a great and high wall with twelve gates, and twelve angels at the gates, and names written on them, which are the names of the twelve tribes of the children of Israel:
Rev 21:13 three gates on the east, three gates on the north, three gates on the south, and three gates on the west.
Rev 21:14 Now the wall of the city had twelve foundations, and on them were the names of the twelve apostles of the Lamb.
Rev 21:15 And he who talked with me had a gold reed to measure the city, its gates, and its wall.
Rev 21:16 The city is laid out as a square; its length is as great as its breadth. And he measured the city with the reed: twelve thousand furlongs. Its length, breadth, and height are equal.
Rev 21:17 Then he measured its wall: one hundred and forty-four cubits, according to the measure of a man, that is, of an angel.
Rev 21:18 The construction of its wall was of jasper; and the city was pure gold, like clear glass.
Rev 21:19 The foundations of the wall of the city were adorned with all kinds of precious stones: the first foundation was jasper, the second sapphire, the third chalcedony, the fourth emerald,
Rev 21:20 the fifth sardonyx, the sixth sardius, the seventh chrysolite, the eighth beryl, the ninth topaz, the tenth chrysoprase, the eleventh jacinth, and the twelfth amethyst.
Rev 21:21 The twelve gates were twelve pearls: each individual gate was of one pearl. And the street of the city was pure gold, like transparent glass.
Rev 21:22 But I saw no temple in it, for the Lord God Almighty and the Lamb are its temple.
Rev 21:23 The city had no need of the sun or of the moon to shine in it, for the glory of God illuminated it. The Lamb is its light.
Rev 21:24 And the nations of those who are saved shall walk in its light, and the kings of the earth bring their glory and honor into it.
Rev 21:25 Its gates shall not be shut at all by day (there shall be no night there).
Rev 21:26 And they shall bring the glory and the honor of the nations into it.
Rev 21:27 But there shall by no means enter it anything that defiles, or causes an abomination or a lie, but only those who are written in the Lamb's Book of Life.
Rev 22:11 He who is unjust, let him be unjust still; he who is filthy, let him be filthy still; he who is righteous, let him be righteous still; he who is holy, let him be holy still."
Rev 22:12 "And behold, I am coming quickly, and My reward is with Me, to give to every one according to his work.
Rev 22:13 I am the Alpha and the Omega, the Beginning and the End, the First and the Last."
Rev 22:14 Blessed are those who do His commandments, that they may have the right to the tree of life, and may enter through the gates into the city.
Rev 22:15 But outside are dogs and sorcerers and sexually immoral and murderers and idolaters, and whoever loves and practices a lie.
