Don't let it. God put His divine nature and power inside your spirit. Your spirit is the new person created like God. Your spirit has all the divine attributes to radically change your life. Many Christians act like the world because their minds have never been renewed with the Word of God.
Worldliness is more than living an immoral lifestyle.
It is living like the world. The world is powerless. God wants believers to live in the power of God. Be transformed by the renewing of the mind. The Greek word is metamorphoo.
