You are

Some people crazy. Don't understand
There ain't no reason in the heart of man
They try and tell me you don't exist
They are mistaken. I must insist

Cause you brought me through the valley
Of the shadow of death
How could you love me like you do
And still have any left

When I've fallen short, when I've gone too far
Everywhere I go, you are

Used to have a soul. Used to have a need
An appetite for you Lord, that lived to feed
Some men are hungry and strongly willed
But at your table, I have been filled

You are in my daytime, & you are in my night
You are everything I need
My Lord and my delight

Straight out of heaven into my heart
And now I know we'll never part
