When you have no faith, it's comforting to be around other people who have no faith. This is why most denominations are so popular. When they say "what faith are you?", they mean what denomination or church do you follow. They are not referring to true, biblical faith. They are talking about faith in man, not God.
If someone gets sick or hurt and the first thing you do is rush them to a doctor. You have no faith. I am not saying you shouldn't take them to a hospital or doctor, I'm just saying your first reaction should be to lay hands on them believing God to heal them. If you go through a tragedy or something bad happens to you and the first thing you do is panic or get depressed, you have no faith. If you or your church does not prophecy, you have no faith.
Being in a church full of people just like you comforts you, because you then feel your lack of faith is normal. People with real faith upset you. They are upsetting the status quo, making you look bad. They're weird! Why can't they fit in like everyone else? Why do they insist on speaking in tongues or, far more importantly, prophesying? Can't they just believe like we do? In other words - can't they walk in unbelief like us?
Don't worry, people of faith don't last long in churches that have no faith, churches that have all the religious trappings of pseudo-faith, who have a form of godliness but deny the power there of. Who's faith is in man, not God.
It's especially comforting to have someone in leadership, someone in authority, validate your lack of faith, indeed approve of it, by having none themselves. This excuses your own lack of faith and it legitimizes you because you can comfort yourself by buying into the "Obedience" doctrine. As long as you submit to and obey your leadership, you are pleasing to God. This excuses you from having a personal walk of faith, from following Christ personally through His Holy Spirit, and allows you to follow man instead, specifically, your leadership, men who have no faith, therefore cannot hear God for themselves, much less for you. They are the blind leading the blind Jesus spoke of and the ditch they lead you into is the grave where their faith has died.
The Holy Spirit is never welcome in a place like this, for He is the source of true faith, as a fruit and as a gift. Miracle meetings are ok it it's a guest speaker that comes in once in a while but true faith never becomes a life style, daily lived. This is more like the pool of Bethesda than a true walk of faith.
So anyone walking in the Spirit is not welcome and will leave or be removed before long - for they are a testimony against their doubt and unbelief and they reveal the true spirit these faithless churches are walking in. The very dust on their feet will testify against their unbelief on the day of judgment.
