Do I Have To Give Money

If I Attend

No.  This congregation is here to serve you with the Gospel of Jesus Christ.  

Besides, it is written that

"Each man should give what he has decided in his heart to give, not reluctantly or under compulsion, for God loves a cheerful giver. And God is able to make all grace abound to you,  so that in all things at all times, having all that you need,  you will abound in every good work.  2 Corinthians" 9:7-8.
