A rainbow is...
A promise
A reminder
A messenger
A connection between Heaven and Earth.
------------------------
I really can't think of a more perfect symbol for our enduring connection with loved ones departed.
I believe there really is a place "somewhere over the rainbow" where my husband - and my friend's baby son, and my neighbor's mom, and your loved ones too - stand and cheer for us, loving us even more strongly than they did when they were here on earth with us. Someday, we'll cross the "rainbow bridge" and join that beautiful gathering.
For now, I'm grateful for healing possible in this life. I'm grateful for promises and reminders and messages of love. And I'm grateful for rainbows.
