Here is a meaning to what the ''Flood'' stood for in the Old Testament.......
quote////Water as a symbol of life as well as a means of cleansing, or purification, is of particular importance in Old Testament.
It was created on the first day (Genesis 1:2, 6-8).
The Spirit of God was hovering over the face of the waters (Genesis 1:2).
The earth was founded upon the waters (Genesis 1:6-7, 9-10).
God commanded the water to bring out an abundance of living souls (Genesis 1:20-21).
In some sense the element is close to God (Psalms 17; 28:3; 76:17, 20; 103:3; 148:4).
God is compared with the rain (Hosea 6:3). Water brings life (cf. Exodus 15:23-35; 17:2-7; Psalms 1:3; 22:2; 41:2; 64:10; 77:20; Isaiah 35:6-7;
58:11) and joy (Psalm 45:5).
It is a powerful purifying element and can destroy evil and enemies as in the stories of the Flood and the flight of Israel from Egypt (Genesis
3:1-15; Exodus 14:1-15:21). According to Old Testament Law, it cleanses defilement (Leviticus 11:32; 13:58; 14:8, 9; 15-17; 22:6; cf. Isaiah 1:16) and
is used in sacrifices (Leviticus 1:9, 13; 6:28; 1 Kings 18:30-39), in which context the Bible mentions the living water (Leviticus 14; Numbers 5; 19).
Water heals, as can be seen from the stories of Naaman the Syrian cured from his leprosy in the waters of Jordan (2 Kings 5:1-14) and the annual
miracles at Bethesda in Jerusalem (John 5:1-4).
John the Baptist used the waters of the Jordan to cleanse people’s sins which reminded typical Jewish custom (Matthew 3:1-6; Mark 1:4-5; Luke 3:2-16;
John 1:26-33) - even Christ came to be baptised (Matthew 3:16; Mark 1:10).
On the other hand, water is also the habitat of serpents whose heads God crushed (Psalm 73:13-14) and of the dragon (Job 41:25; Psalm 103:26).
The story of the Flood is a very popular prototype of baptism. Its origins are clearly shown in 1 Peter 3:20-21 according to which we are to
understand the Flood as baptism and those few who were saved in the ark prefigured the Church of baptised Christians saved by the resurrection of
Christ. In his dispute with Trypho, Justin Martyr expounds the image more profoundly:
The mystery of saved men appeared in the deluge. For righteous Noah, along with the other mortals at the deluge, being eight in number, were a symbol
of the eighth day, wherein Christ appeared when he rose from the dead.
For Christ, being the first-born of every creature, became again the chief of another race regenerated by himself through water, and faith, and wood,
containing the mystery of the cross; even as Noah was saved by wood when he rode over the waters with his household.
By water, faith, and wood, those who are afore-prepared, and who repent of the sins which they have committed, shall escape from the impending
judgment of God (Dialogue with Trypho 138:1-2).
