One would have found a rich array of deities meeting the various needs of individuals in this particular period. In the religious mix of the time, it's very important to realize that one would have experienced institutions and deities who would come from rather remote places. In the Hellenistic period, in the 3rd, 2nd centuries BCE, a number of very important religions that had been distinctive to Egypt and to Syria, for example, began to migrate in substantial ways, in very important ways, throughout the Roman Empire. One would have found in the major cities of the Mediterranean basin a cult of the Egyptian gods. The Egyptian cult and Mithraism were two of the great religious movements of the time and certainly would have posed some of the most difficult competition for Christianity.
Egyptian cults come in a whole host of varieties, but let's sort of take the garden variety.
The garden variety of the Egyptian cult would have included probably Isis as the ascendant deity. Isis was perceived by her devotees as being remarkably attentive. Isis would respond to you when you were in trouble. She would answer your prayers. She had that reputation.
