Genesis 3: 15: And I will put enmity between thee and the woman, and between thy seed and her seed; it shall bruise thy head, and thou shalt bruise his heel.
God promised that one day in the future the right seed would enter the right womb and produce the Redeemer. Eve had the right womb, but she had received the wrong seed by her union with the Serpent and consequently brought forth a murderer (Cain). A little later in the scriptures we read of Abraham who had the right seed, but it was sown into the wrong wombs of Hagar and Keturah, which produced the Ishmaelites and Midianites who became the enemies of Israel. Then Abraham who had the right seed sowed it inside of his wife Sarah. She had the right womb and had received the right seed, but she had the wrong attitude of unbelief, and then lied about it (Genesis 18: 12 – 15).
The right seed and the right womb finally combined when the Holy Spirit overshadowed Mary and produced the Lord Jesus Christ (Matthew 1: 18). After the Angel Gabriel had addressed Mary, the Spoken Word which is the original seed then entered her womb and supernaturally created both sperm and egg to produce the body of our Saviour and Redeemer. Not only did Mary have the right virgin womb to receive the Spoken Word seed, but she also had the right kind of attitude, and uttered these wonderful words in response to the Angel in Luke 1: 38: And Mary said, Behold the handmaid of the Lord; be it unto me according to thy word. And the angel departed from her.
