Should Christians not talk to non-Christians?

Question:

Hello Pastor, and peace be with you this Lord's Day.

I have been studying the book of Romans today and have two questions:

Question 1:

When I sincerely turned to God, I found myself in a certain situation: I became willing to befriend and communicate only with Christians, while deleting or blocking non-believers. I felt as though chatting with those who do not believe in Jesus—especially young people—would somehow contaminate me with sin.

Question 2:

How do I offer myself as a living sacrifice? Does it mean that everything I do must be done for God (Romans 12:1-2)?

May God bless you! I am mindful of your love.

Answer:

"You are the light of the world. A city set on a hill cannot be hidden; nor does anyone light a lamp and put it under a basket, but on the lampstand, and it gives light to all who are in the house. Let your light shine before men in such a way that they may see your good works, and glorify your Father who is in heaven" (Matthew 5:14-16).

How do you teach others if you never talk to them? How do you set a good example when no one sees you?

My relationship with my fellow Christians is stronger than with worldly people, but I still interact with people who are not following Christ. I don't get involved in their sinful behavior, but I don't hide either.

"Do all things without grumbling or disputing; so that you will prove yourselves to be blameless and innocent, children of God above reproach in the midst of a crooked and perverse generation, among whom you appear as lights in the world, holding fast the word of life, so that in the day of Christ I will have reason to glory because I did not run in vain nor toil in vain" (Philippians 2:14-16).
