Where did sin come from?

 Read Genesis 3.

Comedian Flip Wilson was well-known for his skits that used the punchline, “The devil made me do it.”  Some even blame God for their sinfulness or the evil perpetrated by others!  "If there is a God in heaven, why does He allow such awful things to happen?"

 In the perfect environment of the Garden of Eden, Adam and Eve were given complete freedom.  Then Satan slithered in as a serpent.  Revelation 12:9 calls him "...that ancient serpent, who is called the devil and Satan."  Jesus called him a liar and the father of lies (John 8:44).  Do not miss here is Chapter 3, Satan is the source of all questioning of God and His word.  Satan is the one who casts spiritual doubts, who presents wrong desires, and finally outright disagreement with what God has said.  The temptation is there but the choice to obey or to disobey God is human responsibility.

 James 1:14 states clearly, “each one is tempted when he is carried away and enticed by his own lust.”  There is no one else to blame but the sinner.

 Sin separates us from God.  When Adam and Eve sinned, their guilt prompted them to hide from God, attempting to avoid Him.  Their own efforts to cover themselves would not do.  Humans are incapable of restoring that eternal relationship.  All the positive thinking and man-made philosophies, religious and otherwise, may serve as temporary salves or cover-ups for a guilty conscience, but only God can forgive sin and take it away.  

 He offers the one and only remedy.  In verse 15, God proclaimed the first prophecy of a coming Messiah who would destroy the devil and his work.  That is why Jesus came. Matthew 1:21 "...you shall call his name Jesus, for he will save his people from their sins."  He was born to die; born to pay the price for our sin on the cross.  He restores our relationship with Himself through faith Jesus.
