Fables are not useless, imaginary stories. They may or may not be true accounts of happenings of miraculous things, but they do help one achieve miracles. For instance, the whole point in the power of faith, as Voltaire had said, is believing in what is beyond the power of reason to believe.
That means faith enables one to go beyond the so-called impossible means. No wonder, sages through the ages have told us that only the faithful can be the winners and the rest are left to rue. One can have faith in anything, not necessarily only in God. Having faith in one's own ability to overcome problems and do things with vision and determination can be as good as having faith in God. If you believe in the existence of God, then surrender yourself completely to God. But be sure that faith alone won't help you; you have to act too to please God!
If faith can move mountains, then why can't the faithful achieve even the most impossible things? The logic: Faith keeps you always on the positive track and your action and behaviour are directed towards an end that not only gets you success but also a great sense of achievement.
Take this 'faithful' story. Legend has it that saint Thirunavukkarasar changed his faith and turned a Shiva devotee and faithful. The king, a Jain, did not like it and got so angry that he threw the saint into a burning lime kiln. But the saint came out unscathed. He was then thrown into the deep sea with a heavy stone tied to his body. This too failed as the stone turned into a boat to take the saint ashore. Though a fable, it makes one thing sure that faith helps one in all kinds of situations, particularly when one is in deep distress and finds all doors shut.
One must have faith to keep one's dreams alive.
