God and the world

Peace to the rabbi. I finished the series of lessons on God and the World of the Lord and would be happy to provide some clarifications:

1. Why did the Rabbi say that it is impossible to rule out that God intervenes in nature from time to time if this contradicts the sufficient condition? After all, if there are interventions from time to time, then the laws of nature are not always the only condition.
2. What does the rabbi do with the volumes of sage sermons, stories of the righteous, the Bible, and synagogue sermons? I don't mean how the rabbi's method fits in with what is written there, but rather I mean to ask how the rabbi feels when he meets with them, what does the rabbi think, does the rabbi simply ignore the things?
3. According to this method, is there any certainty that in the end there will be good? That we are moving in the right direction from a moral/redemptive perspective or any other parameter of good?
