Culture is a reflection of the religion of a society.
The culture of the unregenerate world reflects their faith against God and all for what the world loves, and behaves accordingly.
The culture of regenerate sons and daughters of God reflect the character of God in an ever progressing fashion, and live their lives in total opposition to the faith and culture of the unregenerate world.
The culture of the regenerate differs. It is separate and obvious. Distinguishable.
The culture of a Christian reflects the character of God, the culture of the unregenerate reflects all that is popular with the unregenerate world.
