Symbolism in the Bible

If we allow it, the Bible speaks to us - just as God speaks to us; for it is the voice of God to those who know their God and know the ways of their God. As the voice of our God - the one who brought us into this world - and the one who will take us out of this world; can we leave unturned any pebble of knowledge or wisdom that voice may offer to us? Or, are we to be open to all that God may put before us - in plain speech - and in the deeper, fuller speech of symbolism in his Holy Word?
