Jews touch the weatern wall because their holiest site is behind it, from what i gathered.
Jesus is touching the wall because he is being tormented? Idk
It must be drawn by a Christian because Jesus wasnt the messiah according to Jewish prophecies.
The thing is, even the Jews will at some point realize that Jesus is the Messiah. That was written about 742 years before Christ was even born:
Isaiah:52 9-11
Wherefore God also hath highly exalted him, and given him a name which is above every name: That at the name of Jesus every knee should bow, of
things in heaven, and
things in earth, and
things under the earth; And
that every tongue should confess that Jesus Christ
is Lord, to the glory of God the Father.
The Jews have had a long history of being disobedient, as can be seen throughout both the Old and New Testaments. But they will eventually come around.
