Oracle

Aristotle tells us in his book Nicomachean Ethics that the goal of virtue is happiness, and in particular the Justice. The whole work of Aristotle is focuses in the development of the idea of how man seeks happiness, happiness is a central theme in the classical Greeks.
Now in the case of Jesus Christ his teachings start from the beatitudes, the beatitudes are promises, the beatitudes are ethical and spiritual affirmations. From the point of view of the Beatitudes the true good is the eternal life, happiness as the goal of life is a false good. In the gospel of Luke there are four beatitudes, Luke 6: 20-23 and four maledictions Luke 6: 24-26.
So, what is eternal life? The spiritual gift of eternal life is a group of blessing, that god give to us in advance of the life in Glory.
This blessings are: the guide of god, contemplation, longevity and the spiritual gift of Consulting.
When we talk about the spiritual gift of Consulting we talk about an oracle.
In the state of communion with God, or to say in the state of integrity,  we can "read" the thoughts of God, a practical case is Joseph divining the dreams of the Pharaoh (Genesis 41:1-44), those who can do this are called oracles. This Gift allows the reveal the thoughts of God.
In ancient times oracles were used to consult about subjects related with the future, the war, marriages, etc.
