The people who believe in Jesus are called His "church," and God promises to be present in spirit where His church gathers. We often set aside special places and buildings for the church to gather and worship God--and we call these places "church," too!
As Christians, we can respect and honor God in what we say and how we behave. In a place of worship, we show respect by treating the space as a "house of God." (But remember: God doesn't live in the building; He lives in His people!) Some of the people in the Bible who experienced God's presence in a special way were Moses (Exodus 3), Paul (Acts 9:3-8), and the 5,000 at Pentecost (Acts 2).
