From Genesis 6, 7 and 8, comes the story of Noah's ark. The earth was filled with violence and God's heart was aching. He decided to destroy the evil on the earth with a big flood. He told Noah and his family to build an ark so they would be safe. Noah made the ark big enough for lots of animals. When the flood was over, God promised to never flood the earth again. The rainbow in the sky reminds us of God's promise.
