  "description": "A fun and colorful design based on the Lord's Rainbow -- a sign of one of His promises to mankind after the flood: Genesis 9:13 \"I do set my bow in the cloud, and it shall be for a token of a covenant between me and the earth.\"  \nThe greater sign now of the covenant between God and man is the cross! Romans 10:13 \"For whosoever shall call upon the name of the Lord shall be saved.\"\nP.S. God is so Good! :)"
