The Importance of Going to a Small Group Church

I started doing evangelism and I just my heart was always sharing the gospel with people. It really just hit me like I have a love for all people and there's no way that this theology is true Because it got to the point where I would hardly witness to a white person Like I'd go months and months and I'd Witness to just Muslims and people in Detroit, which are all different ethnicities. But say your prejudices or confirmation biases from roughly around 70 years of your childhood kind of carried over into that or you had like fight through that.
