I've seen this video as well, and what strikes me is that the things about Yeshua being Messiah that are presented are all coming out of Tanakh. This is a prime way of speaking to Jews in Israel about Messiah, as the B'rit Chadashah Scriptures are often rejected out-of-hand by Jews in general, as a "christian" book, and they won't believe there is any connectibility of it to Tanakh, when presented alone. Even secular Jews will scoff at the B'rit Chadashah and will hold Tanakh as being more reliable in their view. That's why the testimony about Messiah Yeshua - indeed the very glad tidings of the Kingdom of Elohim - must start there.
This is how it is in Israel. One-on-one conversations. There are no soapbox Billy Graham moments in the streets. The conversations are happening, in living rooms, in cafés, in other intimate settings, and elsewhere, even as it was recorded in the Besorot.
Naq`dimon met with Messiah Yeshua in private, as did others in the Sanhedrin who believed. As recorded in the Besorot those in the Sanhedrin who followed Yeshua did so privately for as long as they could. They had intimate discussions about Yeshua and His testimony that - if written down - likely would make the Mishna look like a short story.
