In Biblical days there were Christians, so were their churches like ours?
Their churches were different:
They met in people's homes (the 1st Bapt Church did too in the beginning)
They often had to meet in hiding (I don't think we ever had to do that)
Everyone shared their meals and stuff with each other. ( just let it be known that someone needs our help and we step forward).
Just like in our churches today, we come together to pray, worship and learn how to spread the good news of Jesus Christ to the whole world. You know how good you feel being a christian and how it helps you face the trials of life. So why not share with those who suffer by themselves without the holy spirit.
Spread the word too so they can say" OH, I Got It!!
(Bible reference: Acts 11: 19-20)
