A very large transformation was taking place after these two offerings. Again we can see the word of obedience and disobedience crossing the line of divine rules. Abel's offering in obedience to the teachings reached the Lord's blessing; “By faith Abel offered God a greater sacrifice than Cain.", and attained the grace of the Lord God , and was considered the greatest sacrifice , therefore speaks unto our days of righteousness in obedience to good .
However, the manipulation of the rules of the correct supply of the elements led to the offer of grain from the land of Cain's disobedience and the discovery of food transformation. Burning the fruits of the earth in an attempt to offer the Lord, he transformed the characteristics of food. Man begins to apply his genius and knowledge in evil works, and in the manipulation of all foods of the pure nature of the Lord.
Thinking of deceiving the creator himself the Lord God with this offering, Cain assumed that he would not follow the Lord's guidance. Thus began the transformation of food in Cain. Toasted foods began to please the taste of change, and also the flesh, for these he already kept for himself, for he offered waxes to the Lord, and with these attitudes took away from his own food the characteristics of his natural creation.
With this error of Cain began to disintegrate food from its natural essence, and the transformation of food became a routine for Adam man. Cain's act in offering and disobeying the Lord transformed his altar with grain, into an oven of manipulation and became Cain the first manipulator and food transformer of mankind.
The Lord naturally did not accept the offer, for it was lining his guidance, and it was at this time that Cain discovered that he could also eat these toasted foods. The Lord still tried to correct it, gave him a chance to ask: “If you do well, will there not be acceptance for you?” (Genesis 4:7a).
In this question the Lord wanted to correct it, but the rule was clear, and the Lord says to Cain: “... And if thou dost not well, sin lieth at the gate, and his desire shall be unto thee, and thou shalt rule over him. ” (Genesis 4:7b.c.)
Cain still with this guidance did not want to do good, and became for the “your wish” the first man to begin man's dominion by processed food. Thus at this moment of mankind began the transformation of the food of the pure nature of the Lord into processed foods, besides, of course, the flesh (to eat) that was already part of his meals, for this Cain no longer offered to the Lord God, “because his works were evil”.
But the science of evil in handling food in Cain's life would not be easy for him, because the word states: “When you plow the earth, it will no longer give you its strength;...” (Genesis 4:12a). So all man’s genius has already begun to be proved in this first moment of processing food, and Cain with difficulty with the food and fruit of the earth. This returned even more their desires on the flesh of animals, and so the increase and desire of the flesh would be ever greater throughout the generations of Cain, and the general degradation of mankind began.
