Everyone else did perish but the 8 people on the ark. Other cultures are post flood.
It was also the will of God, that He die and rise again and that His message be the only message on earth one day.
Seems to me Jesus actually said this...
Mt 5:48 - ....as your Father which is in heaven is perfect. He also said this
Mt 5:17 - Think not that I am come to destroy the law, or the prophets: I am not come to destroy, but to fulfil.
And this
Mt 5:18 -For verily I say unto you, Till heaven and earth pass, one jot or one tittle shall in no wise pass from the law, till all be fulfilled.
Jesus confirmed Moses was real and that the law God gave him was valid, and went on to give us a new deal also.
Actually the new testament constantly points out how He fulfilled Scripture and how Scripture is from God and totally endorsed, lock stock and jot and tittle.
The wine spoken of was not Scripture. He was talking to the rigid, made up minds of the killer Pharisees.
It requires rejecting Jesus, so no thanks. I accept what He confirmed was true and sacred and protected by God.
Yet He said He was not happy about the way man turned out after the fall.
The flood was not meant to cure sin or solve the problems of man caused by sin. The flood was a way of dealing with the wicked, that got too wicked. Same thing with Sodom. Same thing with Pharaoh in Egypt. Basically the same thing in all history! One empire comes along, then later another wicked kingdom allowed to take over..etc. Good news though, He is coming to fix it all soon!
