Doubt #4 Man does not inherit a sin nature

Religion wants to be able to work for redemption but our sin nature stand in the way of any works being able to pay for our redemption.  This sin nature was inherited from Adam.  Genesis 5:3 "And Adam lived an hundred and thirty years, and begat a son in his own likeness after his image; and called his name Seth:"  Adam's son was fashioned in Adam's sinful likeness and image.  Genesis 6:5 "And G-d saw that the wickedness of man was great in the earth, and that every imagination of the thoughts of his heart was only evil continually"  Our sin nature came from Adam.
