There is a need for everything to reach a state of equilibrium. When something is in equilibrium, it, by definition, stays there. If it is not in equilibrium, it keeps "moving". Sooner or later it will, perhaps entirely by chance, hit an equilibrium and stay there.


For example, in a cell, the concentration of ions inside and out of the cell are different, which produces an electrical potential- a voltage. This is where you get into the Nernst potential. You should research thermodynamics (entropy etc), it's all just physics when you get down to the nitty gritty of it.
