God created man as a living soul and spirit and put him in a physical body.   

When man rebelled against God he retained his physical identity but lost his spiritual identity.   

Jesus ( God in flesh) came to reconcile humanity back to Himself by giving us a new identity.   

We receive this identity by believing in Christ Jesus and being born of His Holy Spirit.   

So, there are two versions of humanity on earth today:
1.   Children Of God - Born Again believers in Jesus
2.   Corrupted, lost ChildrenOfSatan
