Eve no doubt chafed grudgingly under the sting of her sin as Adam drifted farther from her, paid less attention to her, and became preoccupied with other things. Bitterness, resentment, and rebellion began to settle in her soul. For Adam, cultivating the ground became an endless, tedious chore. Anxiety over his ability to provide for his family added to his agitation and irritability and made him less sympathetic to his wife's needs. As a result, conflict entered their home.
Sin always brings tension, strife, and conflict.
And never was that more painfully obvious to Adam and Eve than when they stood beside the first grave in human history. Their second son had lost his life in an ugly family squabble. This would be the saddest story ever told were it not for a glorious ray of hope by which God illuminated the darkness. God promised that the seed of the woman, a child born into the human race, would destroy the works of the devil, including the havoc he had made of the home. This is the first biblical prophecy of the coming Redeemer.
