Rabbi Tovia Singer stated that Christianity is not a sect of Judaism but is instead a religion of Gnosticism. He also stated that Christianity does not properly address prophetic texts of Isaiah 53 and Jeremiah 31:33 (31:34) because Judaism sees the Messiah differently.

Mark 4- parable of the sower. Question- why does the sower of the word seem to just sow the seeds anywhere?

Mark 4:10-20- Jesus provides parables to non-disciples but they will “not perceive; not understand”). Thought- It is interesting that Satan is as a bird taking seed off a path, because in theory that seed that is eaten will get processed and pooped out elsewhere and still eventually grow and potentially yield somewhere random. Profit seems to be key, yet the sower is not specifically sowing where there will be ideal growing, he is sowing in all types of places. Question- is the sower of the word giving potential opportunity?
