ACTS 2

The apostles got into the habit of eating together, being together and worshipping together. They also gathered in the temple courts together - wow - that was where Jesus had turned over the tables and the place where Jesus had been taken when he was arrested - some of the blood stains on the floor would have been his.

Before Jesus had come to them, they gathered together in locked rooms.
Before the Holy Spirit had come to them, they met together in private.
Afterwards, they met everyday, in public, in the centre of the domain of the people that had killed their Jesus.

Jesus gave them courage.
Do I want courage?
It would mean using it.
Do I actually prefer meeting in a locked room?
