Here are some possibilities:
Colossians 3:1-2 If then you have been raised with Christ, seek the things that are above where Christ is seated at the right hand of God. Set your minds on things that are above, not on things that are on earth.
2 Corinthians 10:3-5 For though we live in the world we are not carrying on a worldly war, for the weapons of our warfare are not worldly but have divine power to destroy strongholds. We destroy arguments and every proud obstacle to the knowledge of God, and take every thought captive to obey Christ,
1 Corinthians 7:29-31 "I mean, brethren, the appointed time has grown very short; from now on, let those who have wives live as though they had none, …and those who deal with the world as though they had no dealings with it.
2 Corinthians 4:18 because we look not to the things that are seen but to the things that are unseen; for the things that are seen are transient, but the things that are unseen are eternal.
Couple other passages:
2 Cor 5:1-9
Philippians 4:8
I thought there was a passage that spoke of being “in” the world but not “of” the world - but I was unable to find any that said that exactly. Closest is Chapter 17 of John’s gospel.
