"Peace is not the absence of war." Spinoza said it, but it is mindlessly quoted out of context, for he added, "It is a virtue, a state of mind, a disposition for benevolence, confidence, justice."
Our guardian angels will be present during the time when our souls will exit this world and abandon the material body. They will be there at the moment to offer us solace and support during that transition and then help us adjust to the realms of the spirits when our soul will be directed toward God. It will be at that point that the soul will become conscious of its eternal condition.
