"And the LORD God called unto Adam, and said unto him, Where art thou?
And he said, I heard thy voice in the garden, and I was afraid, because I was naked; and I hid myself.
And he said, Who told thee that thou wast naked? Hast thou eaten of the tree, whereof I commanded thee that thou shouldest not eat?" Genesis 3:9-11
..........Adam isn't able to respond to God's call. Their fellowship has been broken. Man now responds to his new master, Satan.
