A Sage could mean different things to different people. One example is: a Sage could be the wise old man in the village that everyone goes to for advice. So, one can refer to him as the Sage of the village, or the wise one.

A Sage could be a person full of wisdom, with different talents, and abilities. He may have the gift to heal; he may be able to provide treatment that no one else can give to you. He is highly respected for the work he does, and for some he is the answer to all problems. He could be considered to be the no all to the end all to the ones who seeks his help, and advice. His work to some is everything short a miracle.

In our modern day society, the Sage could be your Guidance Counselor at school, or someone you trust, respect, and you could go to for personal advice and guidance. This someone could help you to work towards your goals to succeed in life, or could help you to solve a difficult problem. Another example is: your next door neighbor could be the Sage, the wise person in your Community that everyone goes to for advice, and help.

It's just a word. It means wise old man.

It is one thing to seek the advice of the sage because you don't know what to do, and you think the sage can help.
It is another to ask god for guidance and god, through your inner feelings, gives you a clear "feeling" that you must ask guidance from the village sage.

Otherwise you maybe seeking advise from the village idiot who is dressed as a sage.
