Cain had a difficult time watching his brother's success and coming up empty on his alter.  He knew he wasn’t the farmer type but thought his gardening expertise would pay off in the end.  He knew God would love his fruit even though the standard had been the sacrifice of an animal.  He worked the soil and did everything he could to yield the best crops he could to give to God.  

Now we know, but people had to learn God was more concerned with obedience than the best offerings man could create.  Unfortunately, before coming to the understanding it was the obedience of his brother God was pleased with, he developed a hatred and an evil bitterness toward him that led to committing murder.  

Cain had a selfish evil desire for two ego-boosting traits:

1.  Recognition

2.  Respect

In our hearts and minds, we can find ourselves longing for the same!
