THE POINT IS THAT JESUS DECEIVED THE JEWS AND THE FATHER DECEIVED BOTH, JESUS AND THE JEWS.<quoted text>
1. When Jesus disappeared it did not cause a physical change on the lives of the Jews.
So there was no deceiving them.
2. It didn't belong to the fish either.
The fish had no use for the coin, and most likely was happy that it was taken from it.
3. No, Jesus was fulfilling the will of the Father, and in those times it was not the proper time to reveal his identity.
Regarding your item 3, it was then not prudent of your deceiving God to have sent him at all. He should not have deceived Jesus and the Jews.
That, in those times it was not the proper time to reveal his identity, is a horrible, foolish, lame excuse and rubbish!!!
