Is it necessary to observe a mitzvah during this time?

Good week
The Rabbi also agrees that God has an interest in this world according to the commandments [as explained in the third book of the Rabbi's trilogy to advance spiritual matters] and therefore every time the people of Israel sin and so on, God reveals himself to the prophet to tell him to turn from his evil ways. Today, and for more than a thousand years now [more or less], God does not reveal himself to anyone, apparently, which really undermines God's interests. And so we see in reality that most of the people of Israel do not observe the Torah and the commandments. The Rabbi does not think that this is a clear indication of common sense that God decided that for a certain period of time, the Torah and the commandments should be observed, and from the period when He stopped prophesying to us, we should not observe them, but only morals [the Rabbi knows someone with common sense who does not care about his own interests]. And it is written that the Torah will last forever and God will return to prophesy. If we keep the Torah, most of the people will, but if the people stop recognizing the Torah and it, they will behave in a reciprocal manner and leave [who remains in a place where they are not wanted?] I am not saying that this is the only possibility to examine things. I am just asking the Rabbi, is this a possibility?
