Trust in God to help the way it was understood in the Mir in NY was to learn Torah and believe that God will take care of things like getting married and having a living. So the idea of sitting and learning even after marriage was along the lines of trusting in God. In Israel however the approach is to make political parties whose sole purpose is to extract money from secular Jews. That is not trust in God at all. But I should add that my idea of learning Torah since then has been expanded to include Physics and Metaphysics because of Saadia Gaon and people that followed his lead in this subject like Ibn Pakuda of the Obligations of the Heart.

But the basic structure of belief I still hold that the Mir was right. Trust in God and do not worry because God will take care of those that trust in Him. That is to say help and salvation is not at all assumed. Rather it is assumed according to the degree that one trusts in God.
The problem however can be that of self delusion. People can imagine that they are trusting in God while in fact being blind to the fact that they are trusting in their political parties to extract money from secular Jews.

My own impression is that God has often helped me whether I trusted or not. So I am not saying what will happen if they think they trust in God. I think people can fool themselves thinking they are trusting in God. But I can say that is one really does trust in God, God definitely helps.
