They don't attend other people church programs when they are invited but they want others to attend their own church programs,
I have banter with several Jehovah's witnesses Preachers who came to my door to preach the gospel. I usually welcome them whenever they come,and will would talk and argue about certain bible scriptures and their interpretations. But alot changed, I had a special program in my church, so I invited one the Jehovah witness who usually comes to share bible lessons with me to my church, he told me plain and simple that he wouldn't come because my doctrine contradict his belief as a Jehovah witness. Without letting him finish with his reasons, I told him to stop coming to house to preach to me. If you can't come to my church and receive bible lessons, then stop coming to my house to share bible lessons with me.
they think less of other Christians churches and hold their own at a very high esteem but at the end I will ask them that is it still one God? If yes then why the discrimination of people that are in the same faith, because of this most of them don't get married at when they are supposed to, they are all holier than holy, everyone have their life and choices to make so I don't judge anyone.
I'm not even interested in anyone holiness since I can't judge who is a more holier or righteous person. I think it is only that has the power to judge who is holy and who isn't, so whether they pretend to be holy whenever they are going out in groups for evangelism is not of my concern. I am more concerned with why they judge other churches doctrines yet they want people to accept theirs as the true doctrine. Who are they to judge others when they themselves aren't righteous?
