According to the story written, God was very sad one day. He saw that men and women have forgotten his teaching and had done a lot of bad things to each other.
God intend to send a great flood upon the earth to wash away all the evil things. But He also wants to keep whatever that is good. He saw that was one good man, Noah, who loved God.
Thus, God came to Noah and told him that a great flood of water would soon cover the Earth. He told Noah to make himself an ark, a ship of wood.
Noah listened in awe and he called upon his three sons and they did as God commanded.
Everyone were laughing at them and thought they were mad. But soon the great flood began. Noah then took in a pair of each animals and birds into the ark. There was a great storm and soon everything was flooded.
After 40 days and nights, the rain finally stopped. Everything were immersed in water.
Noah sent out a Dove and it came back coz there were nowhere to perch.
Then the water started to go down. Again Noah sent out a Dove and it came back with a green leaf. The third time Noah send out the Dove, it did not came back. This Noah knew that soon the water will be gone.
When the water had all gone, Noah opened the Ark's door and all the animals and birds came out.
Then God made Noah a promise that He will never again send down water to flood the Earth and as a sign of His promise, a rainbow gleamed in the sky.
God's word "Love one another". Hard to do but not impossible.
