Sin

In the name of God, the infinitely good and the most merciful

The concept of Sin is the act which is a transgression of God which, can be felt as highly reprehensible. Another definition is that it is a vitated stated in human nature which makes the self, estranged from God.

According to Christianity the coming and death of Jesus redeemed mankind from the original sin committed from Adam. A question to our co-religionist I wanted to ask was in the geneology of Mary I wanted to know where in the Bible (or in history) where she was pure. What I mean is that how did she become pure? According to the geneology of Mary she as a pure woman was the only one without sin and if so, since she  too was born of her parents how did become born without sin?
