This symbol represents the Cup of the New Covenant; the Cup of unbroken relationship.
"Do this in remembrance of ME."
'taste and see that I AM God
The First, The Last, The Same
drink and eat,I'll complete the work for which I came
Living Waters flow from deep within My Vine
fruit of My Flesh, your skin's made fresh
to carry My New Wine
everlasting marriage, by My Own Blood we're bound
I'll never leave, to My Word cleave
your heart's now Holy Ground'
Rev. 1:8,11, 1 Cor. 11:24
