Sin is defined as the corruption of human nature inherited from Adam, encompassing any thought or action not aligned with God's law.
The Bible teaches that sin is the corruption of the nature of every man, naturally engendered from the offspring of Adam. It is described as a moral disease affecting the entire human race, and as articulated in 1 John 3:4, sin is the transgression of the law. Every individual is born with a sinful nature inherited from Adam, who introduced sin into the world (Romans 5:12). Sin manifests as anything in thought, word, or action that is not in perfect harmony with God's divine law, thereby declaring all humanity guilty before God.
