Adam as a Type of Christ

Romans 5:12-21 is used to teach that because of Adam's sin, we all were born with a depraved sinful nature that compels us to sin. However, there is nothing in this passage about such a thing. This passage is about Adam as a type of Christ. As bodily death that came upon all through Adam, even so bodily resurrection from death comes to all through Christ. That as death comes through only one, salvation from death comes through only one.
