I as a Christian….. How can I possibly make friendship/ friends with people who are agnostic, atheists or Non-religious?

I’ve mostly felt comfortable being around Christians, Catholics or any other people who are of any good religion that believes and loves God too.. Especially when it comes to dating or if ever I want to form or be in a relationship or future marriage

I’ve felt uncomfortable because most of my time I don’t know how to form a normal friendship with an atheist or agnostic or a non-religious, and all I tried is to be a good friend to them or love them because I love everyone.

But I’m not comfortable of dating forming a relationship/ marriage with them, not interested. .. All I want is friendship but how can I? Because all I’m used to is talk about Good things and important things in life and God and I understand that you being any type of non religious person or agnostic/ atheist etc I understand that you don’t want me to talk about God. All I want is to help but..
