Do men sin because they are sinners or are they sinners because they sin ??? Just my two cents: I would say men sin because we are sinners...you do not have to teach a young child to sin...it is in his/her very nature...we sin because it is in our nature...we are born sinners, therefore, we do not become sinners once we sin, for we are already dipped in the sinners oil, so to speak. hope this makes sense.
