I invite you to use discernment. It's impossible to know much about anyone without spiritual discernment. I was in at least one church where five satanist plants were exposed after having been in the church for 15 years. It took that long to expose them because no one was using spiritual discernment. They were on guard (the natural state of man to judge everything primarily out of or by his/her need to remain safe from harm), and they only judged those people by outward appearances and how they 'seemed'. Well, they seemed christian but were exposed to be molesting kids, raping women, torturing men, poisoning the church gathering food they always volunteered to make, and cursing people into all kinds of sickness (and maybe death). Spiritual discernment also makes you patient with people and you aren't easily offended. The sinners, heathens, and pagans around Jesus didn't rub Him the wrong way; only the self-righteous religious leaders and people did. christians should strive to be the same.
