Telephones in general relate to communication with and from God. A phone allows us to talk to someone who we cannot see. Cell phones in particular allow for that communication to take place at almost any time in almost any location. With the advent of modern smart phones they also give us access to an almost unlimited source of information (revelation when the communication is with God) and an abundance of resources (Apps) to help us accomplish almost any task that we need to undertake.
