Questioned

it was a harsh night at newton for me. i was being questioned.. 'is christianity real'.
the whole question and answer was a huge battle for me.. cause i don't know much. this led to intense guilt and disappointment. if i don't attend church every week, if i don't attend cell group, if i don't speak in tongues.. can i call myself a christian?
does it matter what church i go to when we're worshipping the same God?
tongues is the communication between god and u. if u can't speak in tongues.. does that mean u can't communicate with God?
it was a lose lose situation for me... the thing is.. questions against christianity is always pretty unfair. for eg: pple would ask.. if you know that the church is earning so much from ur offering.. why do u still give?"
but if you don't offer.. they'd go "as a christian how come u don't give offering".
do you just pray and all ur sins are forgiven?

all this doubts, i could not give a solid answer. and i felt unworthy to be a christian. why am i not able to 'defend' what i believe in.
i too have many doubts about other religion. do i question? No. i respect. i wish the same.
do not question my believe.. because i have something special, Faith.
