Living beings, upon attaining a threshold level of self-awareness, begin to yearn to reunite with their Source. The weird thing is that these living beings initially seem unaware they are literally made up of the substance of the Source. Thus, they do not seem to understand it is as impossible to fear God as it is to fear oneself. Yet the evolution of living sentient beings is eventually defined in terms of the beings' ability to discover this relationship between the original God Source and their own selves. Once this happens, the dominant theme of existence is love. One can love oneself, and all others, because one sees that all of everything is created from the same fabric ... Love is the theme of God, the glue that keeps the universe together.
People have always wondered at the saints, that they are able to walk around serene, whatever happens. But that is because they can choose where they'll be. They don't have to be angry. You see the difference between having scattered emotions and having a fully vibrating, controlled emotional body. This body is made from energy created from choice, from the effort involved in making choices. But it is necessary to practice; then something is possible.
