I am glad to hear that the quote I shared resonated with Nancy Rosebaum. Thank you for letting us know where the quote comes from. The prayer card that it appeared on did not give the original source of the quote. I should look up Heschel's essay "On Prayer" to see what else such a profound thinker has to say on prayer. I will also check out the broadcast on "Approaching Prayer" that Nancy says the quote brought to her mind.
