May God bless you [May you be blessed] with Hope enough to keep sunshine in your love, and Fear enough to keep you holding hands in the dark;
May God bless you with Unity enough to keep your roots entwined, and Separation enough to keep you reaching for each other;
May God bless you with Harmony enough to keep romance in your song, and Discord enough to keep you tuning your love so it becomes sweet music to all who may hear it.
I do not claim to be the original author of this script. I am sharing it like this to make it easier for anyone to use.
