Your neighbor, coworker, relative, friend; is a Christian and you aren’t. Since they are Christian you feel uncomfortable around them. You do whatever to stay far from them because they might start
preaching to you. Does this sound like you?
Allow me to sum up the person you are avoiding. First, the Lord is pleased with that person. Next, that person is going to Heaven. That person is honest friendly and trustworthy. That person loves their enemies and will go to great lengths to treat others in the right way. If you or anyone else is in need, that person will do whatever they can to assist you. They won’t cause you pain by lying or trying to deceive you in some way.
So why are you afraid of them? Why do you want to be around people who are the opposite of what I have described? Seems the problem is you. By shunning decent godly people, you show that you are comfortable around those who endorse and carry out all kinds of unethical actions.
What you need to do is reach out to them. They are good people. Learn from them. Ask them where they attend church and go visit that church. Agree to a Bible study with them.
