There is only one of me; I can only be in one place at one time. And yet my job calls me to inhabit several moments in time simultaneously. This is the nature of rabbinic work.

On the one hand:  today. This is the day that God has made; let us rejoice and be glad in it! I offer a morning prayer for gratitude, I open up my calendar, I scan to see with whom I am meeting today and what is on my to-do list.

On the other hand: Shabbat. I study this week's Torah portion, I prepare verses to read from the scroll, I think about songs and prayers. I pick up my guitar and my fingers automatically go to the chords for our Shabbat melodies.

On yet another hand: the Days of Awe. Now the machzor is released into the world, and I'm having weekly Skype dates with our student cantor. Every time he sings a line of high holiday nusach, the holidays come rushing in around me like waves.

On another hand still: a funeral which took place many months ago, and the ritual unveiling of the headstone which will take place some months hence. A "then" which is past, and a "then" which hasn't happened yet.

I remember preparing the eulogy for that funeral. I remember standing on the cold winter earth. I imagine what it will feel like to return to that spot with the family to dedicate the stone which marks that spot, which memorializes that life.

One of the names for God which we most frequently use is מלך העולם, melech ha'olam, usually translated as "king of the world" or "sovereign of the universe." But the word olam can mean both space and time (as in l'olam va'ed, "for ever and ever.")

My son sometimes asks me at bedtime where God is, and I tell him that God is everywhere. ("But invisible," my son prompts, and I confirm that yes, he's got that right.) God is also everywhen -- present in every moment. Past, present, and future all at once.

It's my job to be in this moment -- if I am sitting with a congregant for a pastoral conversation, they deserve my full presence. And also to be in that moment, and that other moment -- remembering what has come before; anticipating what's yet to come.
