1.Human are selfish. Therefore, they only be good to those who trested them well, just as the saying go "an eye for an eye". We classified those who is not in our favour as enemies. We find it so difficult to love someone who hurt us as we refuse to forgive them because it is easy to forgive man but it is not easy to forgive nature,if some body hurts you then it became difficult to forgive. 2.Loving our enemies only proves you are becoming more like Christ. It is the first initial that we are willing to let go of our anger and frustration towards our enemies.
