Question

I don't understand my friends who shall I call X. X had make a statement means that I am not a a good Christian if I didn't actively involve in a Christian organization and in prayer group. however, is it in the bible that  to be good Christian we must involve in a Christian organization and  not the Church?

From what I know Prayer group is about how we learn from each other and help each other grow. The thing is if attending a prayer group had give me discomfort Is it not good to pray alone for temporary ? Of course I not pray everyday. But I still do.
Pride is a thing that we all have. Is it bad to have pride? I doubt you don't have..Beside not agreeing in some stuff doesn't make you a prideful person is it? It is call having different opinion.
Just because you were careful in listening to sermon and checking on the "source" behind it does it make you a prideful person? I personally think it doesn't disrespect the speaker anyway because in my heart I am only thinking it is true or not the stuff he/she spoke of.
My friend also said something about Leader, If the leader fall it doesn't matter since we all human. Yes I think it true but doesn't the leader effect the whole organisation? If the leader spiritual state not right can he lead others?
Isn't it every Christian duty to get alert from not being swayed away?
Isn't calling people prideful is kind of judgmental when you don't meet eye to eye, and hypocrite to denial you are being judgmental? Further
Denial. Not agreeing on things people said is it call denial when you think it true?
Of course this doesn't include the perception of what I think my-self since perception is vary according to  people.
What wrong with being tradition and not Charismatic?
I have nothing against Charismatic and nothing against speaking in Tongue(though it make me uncomfortable since I don't know what to do when they speak in tongue and I finish praying).
Is it less spiritual?
It is more spiritual when you speak in Tongue?
Growing spiritually is important, but isn't it private thing where people would share when they want to and yes you can ask but can you like after asking then judge you base on your spiritual journey? Aren't we all learning?
Yes you care about me I know but as a person I don't like to be told what to do for my personal life but advise  
and comment are allow since friends are there to correct a brother when they think the brother is wrong. But to me correcting is fine, you can even scold me (I don't mind if you are right) and I will ponder upon them, but never try to pin your opinion on me. I am still human and have my own opinion
