It makes no difference where people of God meet for worship because in the past people met on the mountains, in upper rooms, and houses (John 4:20-24; Acts 20:8; 12:12; Romans 16:5). It also makes no difference how many people come together for worship because it could be two or three. If they are faithfully following the word of God, the Father is pleased (Matthew 18:20).
So don't worry about where the church meets or how many people go there. Take notice of what is taught. Is it the truth from God's word? And do the members practice what they preach? Are the people loving and friendly? Remember that the doctrine is what will save us on Judgment Day, not the church building or the number of people attending there.
Hope to hear from you or see you at services.
