What is a church?
A church is not a building. It is not a denomination or organisation and it is not just a gathering of people.
It is however a gathering of a group of special people who are called Christians. They are people who love Jesus, believe that Jesus died for them on the Cross at Calvary. Who believe that Jesus died paying for all their sins, as a sacrifice to God the Father, so that Heaven is open to them. They are also a people who follow Jesus and seek to serve Him with their lives on earth.
Whenever God’s people meet then Church happens. A building is not required, what is required is a heart to worship God and Jesus through the Holy Spirit together.
Matthew chapter 18 verse 20.
