Those who live as though God sets the rules are not going by their own rules. That is the self-sacrifice, or selflessness, that peace more often than not requires. Those who insist on going by their own rules cannot make that sacrifice. They are the steady adherents of (global) conflict because they are forever fighting both themselves and others to do whatever they think that they want to do.
If you're reading this, I hope God opens incredible doors for your life this year. Greatness is upon you. You must believe it though.
