Only with a parent's mind can we get close to God and True Parents. Parents may have a struggling and painful heart. No one may understand them. They may have to endure hardship until they are tired and broken. They can't express their true heart to their children.
Parents continuously serve and sacrifice with a thankful and hopeful mind toward their children.
A person with a parent's mind offers good things to God and other people. He is eager to work hard and is willing to work without help. He'll do the most thankless and unpleasant job with a thankful mind. We need a sacrificial, serving lifestyle in our life of faith. With such a lifestyle, we will have results that will give us pride forever.
