Well He has not returned a second time as Psalm 2 says...
Luke 24:44-46, “And He said to them, “These are the words which I spoke to you while I was still with you, that all have to be fulfilled that were written in the Law, the Prophets and the Psalms concerning Me.
He went farther in Mat 5, He said heaven and earth have to pass and ALL be done...
Matthew 5:17-19, “Do not think that I came to destroy the Torah or the Prophets. I did not come to destroy but to fulfill. For truly, I say to you, till the heaven and the earth pass away, one yod or one tittle shall by no means pass from the Torah till all be done. Whoever, then, breaks one of the least of these commands, and teaches men so, shall be called least in the reign of the heavens; but whoever does and teaches them, he shall be called great in the reign of the heavens.”
or there is an alternate reading of this passage:
Matthew 5:17-19, “Do not think..."

He did not come to fulfill all prophecies, rather to fulfill the law and the prophets.
He also said in that same context that the law and the prophets is to treat others as you'd like to be treated. Now, consider for example the law about leverate marriage. If you were a woman whose husband had died, would you like to be forced to marry your brother-in-law?
