When God called out to Adam in the Garden of Eden, He knew exactly where he was and where he wasn't when he should have been. When man is out-of-line things go array. Man allowed things to go wrong when he didn't stand up for God when satan came through with colorful language and sweet-talk. Adam got caught up with trying to be with the in crowd. God knew the whole conversation and satan knew what he was doing.
Allowing something wrong to happen and not speaking up puts you in the same company of the wrong.
Then the LORD God called to the man, and said to him, "Where are you?"
It's not really a question...
It's a wake up call.
