Soon, it's kill or be killed. With this mindset, relationships that cannot be restored must be destroyed. This is the ultimate in abusive, brutal power. But people who perform such acts are never safe. Differences that never can be tolerated always will produce fear.
Fear leads to more aggression, more killing, more war.
Perhaps it is with the simple things. Maybe even by sending a greeting card that no longer is expected as war finally exhausts itself on its own carnage. Perhaps we send the card, even though we haven't received one yet. A little thing, but we do it intentionally. Then we are careful not to grow weary in well-doing.
