Why Was Satan Allowed In The Garden of Eden?

This week's question for the Straight Truth Podcast deals with why God would allow Satan to enter the Garden of Eden. Dr. Josh Philpot reminds Dr. Caldwell and listeners that we have previously dealt with the question of why God created the Devil. Because numerous Scriptures tell us that God created everything that exists, all that is and ever will be, we know God created Satan. And because God is omniscient, all-knowing, He knew that this spiritual being would rebel. Sometime after this, we also know that God created Adam and Eve in His image and gave them a beautiful home in Eden. God saw all that He had made, and it was very good. But then, somehow, Satan gains access to Adam and Eve. Why would God allow the Devil to enter this paradise garden after he rebelled? Why would He do this, knowing Satan would tempt Adam and Eve by using a crafty, shrewd creature, which God had also created? Why would God do that?
