In general, these “charismatic” (to borrow a term they might not use) Orthodox Jewish movements are a step in the right direction. God is not a God of gloom, and to mope around is to yield to destruction. God is a God of joy and victory and salvation and hope.
Through the Jewish people, the universal blessing of the Christian Savior came. For a while in the time line of this mortal coil, many of them (at least outwardly) rejected their Savior but unlike what all too many modern Christians believe, God’s unbreakable promise upon them remains. Their Savior is still saving, even those of the Jews who put personal trust upon the Almighty for personal salvation of their eternal lives (as, e.g., the psalmist David did). That’s a hard thing for a lot of modern Christians to swallow, those who are so soft that they still see their faith inextricably tied to a denomination. But Christ never came to make a worldly club with Him as a mascot. That’s a blasphemous idea. He is both very independent and literally sacrificially loving. Everything you would expect out of God.
Well, I lied. A little.
I said God wasn’t a God of gloom.
However, God bore all our gloom. All the gloom of those who have trusted upon Him for the salvation of their eternal lives. And in eternal perspective that gloom is almost nothing, though it may bear heavily and sadly upon us for many mortal years. God’s message to mankind is: “Hang in there. It’s so worth it.”
Christianity really doesn’t differ with Judaism as to the general goals of God with respect to humanity. Where it does differ is as to the means, and about detail of the nature of the Godhead. Christianity fills in a revelation. What Jews treat as Torah today is a mixed bag of divine revelation and fallen human speculation.
