)There is such a thing as trust in God with no effort. But I think the emphasis should go on the first part of the sentence. That is the effort aspect is not as essential as the trust in God part.

) In the Mishna of Rabbi Yehuda Hanasi in Pirkei Avot we find two opinions. One is Torah with work. That is stated in the name of Rabban Shimon Ben Gamliel. The other is Rabbi Nechunya Ben HaKaneh that ''The yoke of work  is removed from anyone who accepts on themselves the yoke of Torah.'' Rabbi Yehudah HaNasi is not deciding the halacha but rather bringing both opinions without a statement which one is right as is his custom in the Mishna.

) And we find that the Altar of Navardok actually had this happen with him. That was the story about the candle in the middle of the night. [He was doing is usual Hitbodadut which in his case meant Hitbodadut in the traditional sense of shaving a hut in the middle of  a forest and spending all day and night alone learning Torah and praying. When his candle ran out, someone knocked on the door and handed to him a candle!

) My own situation was I was in Israel--not doing great but managing. I decided at some point to go with the approach of ''Torah with work.'' That was obviously not happening in Israel, so I thought to get back to California  and do this ''Torah with work'' approach there. That was a disaster. As I was looking for work all the demonic, the religious teachers there told my wife to divorce me because I was not working and learning Torah!! At any rate, I learned a hard lesson about trust in God. If you have a situation in which you are trusting in God and learning Torah and somehow managing, it is mistake to let go off it. And I learned later that this is the universal experience of people that are trusting in God, and then let it go. They fall just as I did.

So what you can see is I think an amazing lesson. You might not be obligated in this level of trust in the first place. But if you have it and let it go, it is accounted as slap in the face of God. Thus if one is a yeshiva or kollel and doing what he knows in his heart for the sake of heaven, then he must not let it go.

) We find in Sanhedrin that Daniel ran away from Nebuchadnezzar because he was afraid of the verse ואת פסילי אלהיהם תשרפון באש [burn their idols in flames] and Daniel thought this could apply to himself after that fact that Nebuchadnezzar had bowed down to him. That is he thought he himself could be considered an object of worship and thus be liable to be burnt. So worship of God must not be confused with tying oneself to a tzadik.
