Christians vs Church folk

Went to bible study tonight. It's a trip how when you hear something you've heard before your mind starts to wonder. I was thinking about the people in church who are there for the church and the people who are there for God. As for me it's a God thing, I can front at home. I can hop on Xbox Live or the internet in general and be as phony as I want to be. But some people I see N church kind of trip me out. Like My pastor has spurts where I can tell he's kind of angry at the fact that we (I'm just guessing) ain't all tithers. I know for a fact that I pay my tithes, ask my tax man. But this trips me out, I've been actively going to church for about two years now and when I first started I thought everybody in there was a super saint.
As for me, I had never really been exposed to church as a child other than the occasional Easter service at my uncle's church. So I didn't really come in to the whole Christianity game with a lot of knowledge. But as a child my mom always taught me the fear of God, she wasn't always super accurate but she scared me into reverence. She'd say things like "God can do anything, he'll strike you down where you stand". Or "He'll make it to where everything you do will fail". So I had a genuine FEAR of God like he was a big Freddy Krueger in the sky. So when I get into church with all these people who I assume have read the Bible 3 or 4 times and can quote any scripture at the drop of the hat I'm intimidated by their righteousness. I'm like "Dang, I hope they don't ask me no Bible questions or nuthin' cuz I don't know na'n". I go through the whole thing of accepting Jesus and make my best attempt to live my life upright and I assumed that everybody was and beyond. I figured we were all here to please God and learn more about him but I'm not too sure anymore. Sometimes it's like whatever the pastor say people are getting all riled up. Like he'll say "God wants to bless you" and people go 18 bananas. Not saying it's wrong to praise God in his house but it seems like some people ain't even listening. They just waiting for an opportunity to trip out. Like,(I say like a lot[sorry]}) I go to church to hear the word of God and hope that the pastor can give me some insight from the scripture that I may have missed out on during my personal time of reading. Others seem to be there just to show out and be in company with other folk who wanna show out. There are times where my pastor will do a whole message that he's done not that long ago, or tell a story we just heard the other day and they're laughing and jumping up and down like it's something new. Are all the lights on? We just heard this at Monday night bible study, it's only Wednesday did you forget? It's kind of annoying. Especially the thing with the tithe. The Bible says that the tithe is holy and is one of the highest forms of worship. So why when it's time to sing and dance folk turn the church into Club Jesus but when it's time to give a dime off of ya dollars you gracefully bow out? It trips me out, especially being the type of dude I am. I take pride in the fact that I keep it 100 100% of the time. I may tell a lie here and there to protect someone's feelings but I repent. I'm not saying I'm without sin but I acknowledge the fact that I may not have the nicest mouth in the world but I do live for Christ and do my best to please God. A lot of church folk seem like they just wanna appear righteous until it's time to go home. Super saint around other church folk until you get home to them Newports. It's kind of funny and sad at the same time. I know a lot of the people at my church personally and especially in the case of my wife's parents, they really holdin' it down for the Lord. Others, not so much. I just trip off how my perception has changed over my two years as a real God-fearing, tithing, tongue speaking believer. I thought all church people were God people, I guess not. Sorry if I offended anybody who reads this but if you really there for God then this ain't for you. What do you think?
