You can love your enemey before you know them.
But if you know them, they won't think you are being nice to them because they are getting one over you, but are actually loving them anyway.
One of the things you will come across.
The Holy Bible says that those who return evil for good will never have evil leave their house. That isn't limited to people who recognize their enemy, but also to those who are innocent of knowing everything about the wicked around them.
Whoso rewardeth evil for good, evil shall not depart from his house.
And for the support of this Declaration, with a firm reliance on the protection of Divine Providence, we mutually pledge to each other our lives, our fortunes and our sacred honor.
