Why did God allow Satan to tempt Eve?

The first man and woman chose evil over good, but only when Satan approached Eve (and Eve offered the sin to Adam, which he took on for himself).  But why did God let Satan approach them?  Why didn’t He strike Satan dead?  He could have.

Have you ever seen a parent whose goal in life seems to be to keep their child away from all dangers?  Don’t use a knife, because you might cut yourself.  Don’t use the stove, because you might burn yourself.  Don’t use the car, because you might get in a wreck.  But there comes an age when a child needs to use a knife, stove, and car.  It would be pretty hard for a twenty-year-old to get around without these skills.

The knife, stove, and car aren’t bad.  Bad choices can be made with them, but good choices can be made, too.

God doesn’t keep Adam and Eve away from all possibility of danger.  He gives them choice.  Isn’t that interesting?  The same God we sometimes worry about not giving us choice actually gives choice to Adam and Eve right away–and to us.

Oh, what a miserable person I am! Who will free me from this life that is dominated by sin and death? Thank God! The answer is in Jesus Christ our Lord. (Romans 7:24-25a, NLT)
