The sin nature makes us rebellious to God. Humans have a natural tendency to sin.Human nature has never changed (the temptation of Adam and Eve proves that). Jesus had the same human nature you and I have.
Prior to the fall..not so as A&E were created very good.
God created man in His own image,...not a sinful image. Since the fall Adams progeny has been made in Adams image mixed with Gods image...the image has been smeared.
Jesus was born of a virgin and by-passed the Adam linage/image.
At the resurrection we will be raised uncorrupted...no sin nature.
