"Do not love the world or the things in the world. If anyone loves the world, the love of the Father is not in him. For all that is in the world—the lust of the flesh, the lust of the eyes, and the pride of life—is not of the Father but is of the world. And the world is passing away, and the lust of it; but he who does the will of God abides forever." (1 John 2:15-17)

"And do not be conformed to this world, but be transformed by the renewing of your mind, that you may prove what is that good and acceptable and perfect will of God." (Romans 12:2)

"Do not be unequally yoked together with unbelievers. For what fellowship has righteousness with lawlessness? And what communion has light with darkness? And what accord has Christ with Belial? Or what part has a believer with an unbeliever? And what agreement has the temple of God with idols? For you are the temple of the living God. As God has said: “I will dwell in them And walk among them. I will be their God, And they shall be My people.” Therefore “Come out from among them And be separate, says the Lord. Do not touch what is unclean, And I will receive you.” “I will be a Father to you, And you shall be My sons and daughters, Says the Lord Almighty.”" (2 Corinthians 6:14-18)

"Therefore do not be partakers with them. For you were once darkness, but now you are light in the Lord. Walk as children of light" (Ephesians 5:7-8)
