Value systems are thinking systems that define what is ethical and moral, The thinking systems vary from place to place, and among individuals. They collectively form moral expectations that are learned and pursued by the members of that community.
The value system of the world emphasizes the pursuit of happiness, success, and accomplishments. The value system of heaven, on the other hand, emphasizes on your identity and relationship with Jesus Christ.
The former is transient, while the latter is eternal. As children of the kingdom of heaven, we are governed by the value system of heaven. Although we are on earth and are under the pressure of the value system of the world, our eyes are fixated on Christ, who is the author and finisher of our faith.
