"If God is perfect, why did He make an imperfect creation?"

The Bible tells us that the Genesis creation was "good." There was no sin and therefore no suffering or death. Why then did God give Adam and Eve the ability to sin, knowing full well that they would sin and bring death and pain to the human race? Some believe that if Adam had been created without the ability to chose, then he would have been a "robot." A father cannot make his children love him. They choose to love him because they have a free will. Others point out that humanity would never have seen the depth of the love of God, as displayed in the cross, unless Adam had sinned, and that fact could be one reason why God allowed sin to enter the world.
