Article: In a broad sense, "sin" refers to anything that falls short of the holiness of God. The easiest to spot are usually actions, but sins can also include thoughts and attitudes.  Certain actions are considered sins, but the desire to perform those actions is sinful, as well. For instance, wanting to commit adultery is a sin just as actually committing adultery is. Temptation is not a sin, though. If you're put in a compromising situation with someone you find physically attractive, you may feel tempted to act on that attraction. Actually acting on that attraction and committing adultery as a result, or imagining the act of committing adultery even without doing it, is the sin. Simply feeling tempted to do so is not. Even though mankind was created in the image of God, the fall of Adam and Eve—the first humans—signified the fall of all humanity. As a result, humans are sinful by their very nature. In other words, you don't have to be taught how to sin. Sin is already firmly fixed inside of you at the very core of your being from the time of your birth. When Jesus died on the cross, He carried the sins of humanity with Him. Christ's sacrifice canceled out the debt of original sin. In the Old Testament, animal sacrifices were used as a way to repent for the sins of flesh. Even these sacrifices were imperfect, though, so the stain of original sin still remained. As both Son of God and Son of Man, Jesus became the “perfect sacrifice,” capable of freeing the human soul from the chains and punishment of original sin. " Accepting Christ and being freed from sin does not mean that you will never do another wicked thing ever again. Christ's sacrifice freed your spirit from the shackles of sin. Your flesh—including your body, mind, and heart—will still have to deal with everyday sin. Your soul can be free from sin even though your body still sins. Being free from sin on a soul level should mean that you also seek freedom from sin on a physical level, though, even though it can never be permanently reached.
