The problem with blithely repeating "don't be afraid, Hashem is in charge and is taking care of us" is that when, inevitably, bad things happen, where is your bitochon? There has to be room for the understanding that painful and frightening things happen to faithful Jews all the time, and Hashem does not guarantee that bad things won't happen to us—especially, especially, especially as consequences for our collective behavior as a people.
So when I see our people endorse violence and corruption—in the name of Hashem, no less!—of course I'm afraid. How can I not be afraid when we are worshipping the idols of money and power and nationalism and calling it Judaism? When we daven every day and afterwards tell the widow and the orphan in our cities that it's their fault?! We are on a collision course with Hashem. Again, just like before. And like before, we are full of certitude and self-righteousness as we do it.
I think that we don't have prophets anymore because there's nothing new for a prophet to say. Just read this through the end of the chapter:
Yeshaya 1:10
שִׁמְע֥וּ דְבַר־יְהֹוָ֖ה קְצִינֵ֣י סְדֹ֑ם הַאֲזִ֛ינוּ תּוֹרַ֥ת אֱלֹהֵ֖ינוּ עַ֥ם עֲמֹרָֽה׃
Hear the word of GOD,You chieftains of Sodom;Give ear to our God’s instruction,You folk of Gomorrah!
