This is a pagan idea, not a Biblical one. If it is argued that God would not have created the serpent because of the great sin it enticed Adam and Eve to commit, remember that sin entered the world from man (Rom.5:12); the serpent was therefore amoral, speaking from its own natural observations, and was not as such responsible to God and therefore did not commit sin. Some suggest that the serpent of Genesis 3 is related to the seraphim.
Hili ni wazo la kipagani, sio la Biblia tu kama ukitiwa mkazo wa kwamba Mungu asingemuumba nyoka kwa sababu ya dhambi kubwa aliyomshawishi Adamu na Hawa kuitenda, kumbuka dhambi iliingia ulimwenguni kutoka kwa mtu (Rum. 5: 12); kwa hiyo nyoka kuwekwa kujua baya na jema alinena kutokana na kuangalia mwili wake, na kwa hivi hakuwa na la kujibu kwa Mungu na kwa sababu hii hakutenda dhambi.
