On one hand, we suffer the consequences of Adam's disobedience and have inherited a sinful nature from him (Rom. 5:12-23). The Bible states that ". . . through one man sin entered into the world, and death through sin, and so death spread to all men, because all sinned," (Rom. 5:12 - all Bible quotes are from the NASB). Adam sinned. We didn’t. He was in the Garden of Eden. We were not. When we face God on the day of judgment, the Lord won’t say to us, "Adam sinned, so you are going to pay for it." We are responsible for our own sins, not the sins of others.

On the other hand, we are affected by Adam’s sin. This is how. Before the fall, Adam was sinless, perfect, and good (Gen. 1:31). He had a ‘good’ nature. But, after the fall, he became a sinner. His nature was changed from ‘good’ to ‘bad.’ Since we are his children, we inherit his sinful nature (Rom. 5:12). In this sense, we suffer for what Adam did; that is, he caused his descendants to have sinful natures and all of us suffer because of it. This is called original sin. It means that we have inherited a sinful nature and that all of what we are as individuals (mind, body, soul, spirit, emotions, and thought) is touched by sin. But this does not mean that we are as sinful as we can be. After all, God has written His Law on our hearts (Rom. 1:19; 2:15).

In addition, creation was also affected by the fall. God had given dominion of the world to Adam. Adam sinned and sin entered the "world" as it says in Romans 5:12. That means that death entered the world along with disease, pestilence, earthquakes, famine, etc. They all have their root in the fall. That is why the Bible states that creation is longing for its redemption (Rom. 8:18-22).
