Are you sure? I have read many years that there is nothing whatsoever to do. Simply "be". Or just "be the church". :)
Such sentiments are well intended and like many errors they have an element of truth. Yes, the church is the people - not the building. And yes, we can only obey God by his strength and Spirit in us.
Let's prove all things and whatsoever we DO - DO all to the glory of the Lamb.
