As I travel, I ask this question and simply listen to other Christian leaders define church. The answers are intriguing.
What I hear most is that church is beautiful and amazing. Jesus made church so adaptive to what she needs to be that she can go into absolutely any situation and live well. Jesus’ work in giving us church is great.

I do not read where Jesus used land or buildings or even numbers to define church, except possibly in Matthew 18 where Jesus said “where two or three are gathered.”
