The money Hungry church

I attended this church for about 4 years. I enjoyed the worship and preaching. But I noticed some false doctrine and manipulation techniques to get people to tithe and sow seed. The pastors live lavish life styles and fly first class on the people tithes. I started hearing the pastors preach that you must secure your salvation with the tithe. This is totally unbiblical from mainstream Christianity. I had a meeting with a certain pastor to discuss this, and was told salvation is free but to keep your salvation you must tithe and if I'm not happy I can leave. So be careful of these cult like tactics. Are they after money and not souls. ?Beware if you dont want spiritual abuse. !
