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.
No human being will ever have a better friend and confidant than his or her angel. Even in little things, they are always there to help you in distress, pain, unhappiness, or indecision. There is never a time when your angels are busy at something else and do not hear you; their whole concern is you and are always "on tap." Their line is never busy.
