Genesis 3, God walking around the garden

In genesis 3:8 it reads, "When the cool evening breezes were blowing, the man  and his wife heard the Lord God walking about in the garden. So they hid from the Lord God among the trees".  I envision God as an entity and not a physical being.  This passage stumps me.
