When you followed your parent's guidance to share with your siblings, you realized that there are people other than yourself. And when you shared, you felt the joy of approval from your parents, appreciation from the one with whom you shared, and satisfaction from a good conscience. Obedience to parents is a preparation for harmony in society. Through the extended family, one learns to love one's elders. Elders can be regarded as aunts, uncles and grandparents.
Society becomes an extension of the family.
This ability to love all people, developed through adolescence and adulthood, brings peace to yourself and your surroundings. Although you received tangible rewards and approval as a child, you graduate to higher levels of serving where the rewards are not so tangible. This culminates in a life full of meaning, and prepares you to serve God, whom you cannot see but to whom you are learning to ultimately relate. As you grow, you wonder about eternity, about the origin of the universe, and about the nature of the Creator. Awareness of the invisible Creator and the ability to work in harmony with Him is a profound experience.
