As Sure As Air:

Yes I know you do exist
Though I've never seen your face,
Because I feel your presence
Everywhere and every place.

Your tranquil and transparent
And your always available,
So everytime I need you
Your faithfully attainable.

Never have you forsaken me
Your my source for survival,
For without your very essence
My livelihood would spiral.

Your my pick me upper
You give me cause to breathe,
For you energize my Soul
So in you I do believe.

Your my most lucid alliance
That I have yet to see,
To ever enrich my inner core
And set my worries free.

So God I know you do exist
For your as sure as air,
Though either of you I haven't seen
I know you both are there.
