Don't blame me, I didn't eat the fruit
The Bible says that all have sinned as we have all inherited a carnal nature. When Adam and Eve ate the fruit of the tree, it shined a light on our sinful nature. This is why we all need Jesus Christ as our saviour.
Even though we weren't in the Garden of Eden, we would have eventually done what Adam and Eve did and eat the fruit. Why? Because of we all have a sinful nature, separate from God.
The solution is Jesus and his perfect sacrifice. The blood covering of Jesus means that God doesn't see our sin, and we can be presented blameless to God.
‘Repent, and be baptised every one of you in the name of Jesus Christ for the forgiveness of sins, and you shall receive the gift of the Holy Ghost.’ Acts 2 v 38
