Adam was created by God for the purpose of communing, fellowshipping and multiplying in a wonderful garden relationship forever. Adam was a perfect creation made to function perfectly for eternal earthly bliss.
Adam interfered with God’s plan and chose to destroy the eternal garden relationship, through an act of rebellion and disobedience. Through Adam’s fall, death entered the scene along with Satan’s entire inventory of tactics designed to bring an end to mortal life. Through Adam’s error, Satan gained entrance to impact all of Adam’s seed. Satan’s purpose in all his endeavors is covered in half of one verse in God’s Word.
