If one cracks their knuckles whenever they have soda, they can try the difficult route of trying to focus and not crack them, or they can stop having soda, and there won’t be any issue in the first place.
The Jews in Egypt were idol worshipers. They left Egypt, and shortly afterwards they were all receiving prophecy! How did they do that? How did they change so quickly from so deeply under the influences of the Egyptians to such holy people?
The answer lies in the fact that the Jews never intrinsically became “idol-worshipers”. They did the act, but it never became a part of them. As soon as they were out from under the influence of the Egyptians there was no turn-around that had to be done. The bad influence was gone and so were the effects of it.
