if my prayers held hands i hope they'd circle the earth

i was thinking about the people i wanted to remember by prayer tonight, and i felt a little overwhelmed by the number of people in my heart. then, paradoxically, i felt a surge of desire to pray for everyone i know, which led to wanting to pray for everyone i don't know, and not generically but by name. how do i draw the line? how do i ever stop pleading for grace?
