What is a friend? A single soul in two bodies. (Aristotle, 4th century BC Greek philosopher)
Mencius, a Chinese philosopher of about the same period, put it this way: “Friendship is one mind in two bodies.” That is a really close friendship. We probably have a lot of friends, but only a few will be that close—people we can fully reveal ourselves to and trust completely. With such intimate friendships, we can both recognize each other’s faults and lovingly correct them.
A friend is always loyal… There are “friends” who destroy each other, but a real friend sticks closer than a brother. (Proverbs 17:17; 18:24)
