Info & reflection: The parallel structure says it all: God's slowness is not absence, it's the same patience working in both directions, grace and mercy as one thing.
Note on the attribution: The quote circulates on social media attributed to Rumi, but it can't be traced to any Persian text (neither the Masnavi nor the Divan-e Shams). No verse, no page. Probably anonymous: it follows the pattern of false Rumi attributions documented by scholars such as Ibrahim Gamard.
