How do we know the church is a local body?

The consistent use of the word 'ekklesia' in the New Testament points to a local and visible congregation of believers rather than a concept of a universal or invisible church. For instance, in Acts 20, Paul addresses the elders of the church in Ephesus, specifically referring to a local assembly with designated leaders. This signifies that the church is meant to be localized, with pastors and elders appointed to oversee the spiritual well-being of that particular group. This understanding challenges prevalent views that diminish the importance of congregational life.
