This chant pulls worship up and out of my soul like no other. And the tears too, yes, but when worship is pulled up, the tears oft are pulled right along.
Try singing along with this and see if the same doesn’t happen to you (it’s repetitive, so you can catch the words easily). I find that my most full-throated singing is set free. It was recorded within the Hagia Sophia in Istanbul.
“For His mercy endureth forever and ever, Alleluia!”
