The commandments, "Do not commit adultery," "Do not murder," "Do not steal," "Do not covet," and whatever other commandment there may be, are summed up in this one rule: "Love your neighbor as yourself." (Romans 13:9)
We are well aware of the story of Cain and Abel and how Cain killed Abel, his older brother. This murder was not accidential. The feeling of hatred became emboldened and finally caused Cain to kill his brother. The bible tells us hatred is the act of murdering. In the same way, let us control our emotions and endeavor to get rid of any feeling of dislike toward our brothers and sisters.
