Those overarching colours of the spectrum always signify promise: the rain does end, the clouds do break up, the sun remains even if partially hidden and will soon burst forth. Its peeking through even while the clouds and rain remain produces such an unlikely arc of brilliance and colour even the most unbelieving heart has to smile at the show.
Biblically, the rainbow was to be a sign of God’s covenant of love between Himself and all living creatures on earth. No more village-sized wooden arks would be needed for flood protection.
More rainbow quotes:
“And when it rains on your parade, look up rather than down. Without the rain, there would be no rainbow.”
No ideal, and you're lost;
Your heart must ever cherish
Some faith at any cost.
Some hope, some dream to cling to,
Some rainbow in the sky,
Some melody to sing to,
Some service that is high.”
―Harriet Du Autermont
“Weekends are a bit like rainbows; they look good from a distance but disappear when you get up close to them.”
“Don't miss all the beautiful colours of the rainbow looking for that pot of gold!”
