During their period of growth, Adam and Eve loved each other as brother and sister, not as husband and wife. Upon receiving Lucifer's knowledge, Eve realized that her rightful mate was not Lucifer but Adam.
No longer innocent, Eve realized the seriousness of her transgression and desired to recover her previous position in God's favor. She thereupon tempted Adam to behave as her husband. Adam responded and had relations with her prematurely (Gen. 3:6).
Thus, they disobeyed the command of God. Adam felt the same fear as Eve did, and through the knowledge received from her, he herecognized his sinful act.
They were ashamed of what they had done, concealed their lower parts, and hid themselves. (Gen. 3:7-10) By transgressing God's will through their act of fornication, Adam and Eve fell far below the Formation Stage, both spiritually and physically, and became subject to Satan's rule.
