hi northern,
i was reading your post and i suddenly remembered the verses God gave me in philippians when i was praying one time and seeking direction. it says, "in everything you do, do all for the Lord"...
i am a teacher by profession, i teach kids. im in a foreign country and have been attending this church. like you i have this desire to serve God in ministry as i used to do when i was in my country. i was part of the worship team and i sang in the church band. but at the moment, i dont know what my place is in the church i am now except as a pew filler, as you call it.
however, i know i dont have to be part of any minstry in church to serve God. in everything i do, i can do it all for the Lord...whether i teach kids, or do something for friends, or do some work at home.
an elder in church once told us, a street sweeper can sweep the streets in the same way michelangelo painted. it is said that michelangelo was a christian. a story goes that one time someone told him why he has to put so much detail in some parts of his work when no one can see. and michelangelo replied, "but God sees".
a pastor once told us that many people mistake serving God as having a place of ministry in church, but that is not always the case. each one has his or her own calling. there is much you can do for the Lord in all the everyday things...
but again, seek God
