I call upon Thee

A phrase today from a churchy-type service:
Yahweh, Allah, Gaia; Yemaya, Zeus, Kimet--I call upon thee, whose influence I need right now.

So.  We call upon the god whose traits we need to guide us in a particular moment or situation.  Not unlike the Greek gods and goddesses.  Baking?  Call upon Hestia.  Going into battle?  Athena, Aries or Artemis.  Love woes?  Well, you know.  So, in today's pantheon of monotheisms, do we still call upon a particular deity for the same reason?  The Christian god is merciful (now) and we pray for mercy for ourselves or that we may be merciful to others, and need a little help with that.  Or patience like Job, or various other purges and influences.  Judaism focuses on the Master of the Universe through whom all things flow.  These are monotheistic deities after all, they must encompass all the traits we will need.  Which means they are all basically the same.  So what, then, draws us to one religion versus another, if not a particular deity for its trait?
We grow up Christian and become Buddhist.  We grow up Catholic and become Atheist.  We grow up Agnostic and are Born Again.  I think the truth is that we still do seek out what traits we need.  As we grow, sometimes our faith grows with us (for all those Catholics who are still Catholic,) and for others, we grow into our faith, into our new god.  Or we find our faith in other places, still in light and kindness, but without name.
I guess the point, really, is only this: recognize, take notice, of the act of calling upon that thing which you need.  Are they not all equal in the asking?  Of course they are.  So just mark the action, understand that we do this, that we ask for whom we need by what we seek.  Focus not on the prayer, on the problem, but the simple act of the asking.
