the Bible is not written in the style of
a modern book it has a method all its own of conveying knowledge through picturesque symbols
the reason being that this is the only possible way in which knowledge could be given to people in all ages in different parts of the world
and of different degrees of Spiritual Development
a direct statement in the modern manner would appeal to a particular kind of audience but a symbol appeals to any audience...
when one can discern the symbols apply to the inner self of mankind

Matthew 13
34 Jesus spoke all these things to the crowds in parables.
He did not tell them anything without using a parable.
35 So was fulfilled what was spoken through the prophet:

“I will open My mouth in parables;
I will utter things hidden since the foundation of the world.”
