Human Depravity
Because a perfect God can do nothing less than create a perfect world, God created all things perfect. But due to the fall of humanity through a misuse of free will, sin entered the world, wreaking havoc. Since the fall of Adam and Eve, people are born with a sin-nature. Every human being—except Jesus Christ—has been born a sinner. And because of this, Christ’s redemptive mission is to save us from our sin and establish a right relationship with God.
Why? Because humans are unable to earn our own salvation. Furthermore, if there was no sin, Christ’s mission would not be unnecessary. Therefore, human depravity is an essential doctrine because it deals with humanity’s need for a Savior.
