Just because the world will one day end, doesn't mean it's definitely heading toward the end now.If it's not heading toward the end now, it could get better. And if it could get better--we ought to be working toward that. Being in the Kingdom is about being bringing a blessing of life, no matter what the long-term future is. God will destroy his enemies. He doesn't tell us to do that. Instead, he tells us to heap kind words, prayers of blessings, and good deeds on our enemies.
