My guess is that the sign meant heaven. But to me, God's place is everywhere - these are some lyrics from a Third Day song that is called, funnily enough, You're Everywhere -
Your're everywhere
Like the rain that's falling
Your're everywhere
Like the wind that's blowing
Your're everywhere
Like the sun that's on my face
I feel the warmth in Your embrace
Your are everywhere
I think that sums it up for me.
