How do you interpret Matthew 5:17 - 5:18 regarding the Jesus update? Isn’t this Jesus saying that the old testament still stands?

I guess the odd thing is, if the orange portal can be moved, the pressure from the brick wall would be directed at the attachment point of the orange portal, otherwise why wouldn’t the orange portal keep moving, since it is not “touching” anything?

If the blue portal was deep under water, the pressure would force the water out the orange portal.

The problem with this analogy is that both sides of the window are at the same point in space so there is no pressure differential. What if the blue portal was at the bottom of the Mariana’s Trench? What force displaces the water to place the cube on the other side?

What if the blue portal is at the bottom of the Marianas Trench?
