In Genesis God 3:1-19 we find that eating a fruit was not the original sin. Adultery – as an act resulting from disbelieving God’s Word was. One would naturally ask how the serpent could have had a sexual union with Eve? While in our present understanding the serpent is a snake, we note that it was only after God cursed the serpent that he became a snake. “Upon thy belly shalt thou go (he didn’t go on his belly before this) and dust thou shalt eat all the days of thy life” (Genesis 3:14). We are told that before this he was more subtle than any beasts (not reptiles) of the field (Genesis 3:1). He also could talk, reason and persuade (Genesis 3:1-5). The consequences for Eve are stated in Genesis 3:16 “Unto the woman he said, I will greatly multiply thy sorrow and thy conception; in sorrow thou shalt bring forth children; and thy desire [shall be] to thy husband, and he shall rule over thee”.

Science to this day is looking for that elusive ‘missing link’ between the animal kingdom and the human being. This has not been found, because there is nothing in a snake to identify it with its original form before it was cursed.

The serpent, possessed by the devil, able to talk, subtle and beautiful, referred to as the tree of the knowledge of good and evil perverted the Word of God and presented this to Eve. Lying to Eve he said “Thou shalt not surely die” (Genesis 3:4) after God had already spoken to Adam “But of the tree of the knowledge of good and evil, thou shalt not eat of it: for in the day that thou eatest thereof thou shalt surely die.” (Genesis 2:17). The devil is a liar, (John 8:44) and called by the Lord “That old serpent and Satan” (Revelation 20:2).

Man in the Bible are often likened to trees (Palsm1:3, Jeremiah 17:7-8, Isaiah 61:3), and we are the fruit of our mother’s womb (Psalm 127:3). In Proverbs 30:20 we are told that “Such [is] the way of an adulterous woman; she eateth, and wipeth her mouth, and saith, I have done no wickedness.”.
The result of this disobedience was an immediate recognition by Adam and Eve that they were naked (Genesis 3:7) and they took fig leaves to cover their nakedness.

The fruit or result of Eve being sexually known by the serpent and by Adam was that she conceived Cain and Abel. Life comes only from God the Creator and as Abel was the son of Adam, so Cain was the son of the serpent. This is confirmed in 1 John 3:12 “Not as Cain, [who] was of that wicked one, and slew his brother. And wherefore slew he him? Because his own works were evil, and his brother’s righteous”. The serpent is further indicated as Cain’s father when Cain murders his brother Abel. This murder was the result of jealousy because God accepted the blood sacrifice offered by Abel which he understood by revelation. Cain’s sacrifice, the fruits of the ground was rejected by God. Right from the Garden of Eden, blood is the accepted cleansing for life, both physical and spiritual, pointing to that perfect sacrifice when the blood of our Lord and Saviour Jesus Christ, the lamb of God was shed for our sins. Attentive scripture readers will have already noted that God took animal skins to cover Adam’s and Eve’s natural nakedness; “Unto Adam also and to his wife did the LORD God make coats of skins, and clothed them” (Genesis 3:21).

What does the scripture tell us about who was the father of Cain and Able? In I John 3:12 the scriptures helps us to understand why Cain is nowhere in the genealogies mentioned as Adam’s son: 12 Not as Cain, [who] was of that wicked one, and slew his brother. And wherefore slew he him? Because his own works were evil, and his brother’s righteous. When Jesus encountered His opponents, He identified them by pointing back to the Original Sin. John 8:39-41 39 They answered and said unto him, Abraham is our father. Jesus saith unto them, If ye were Abraham’s children, ye would do the works of Abraham. 40 But now ye seek to kill me, a man that hath told you the truth, which I have heard of God: this did not Abraham. 41 Ye do the deeds of your father. Then said they to him, We be not born of fornication; we have one Father, [even] God. (Fornication being an illicit sexual relationship). John 8:44 Ye are of [your] father the devil, and the lusts of your father ye will do. He was a murderer from the beginning, and abode not in the truth, because there is no truth in him. When he speaketh a lie, he speaketh of his own: for he is a liar, and the father of it.
