As

The Lord's prayer and our participation require child-like faith.

As
your kingdom come, your will be done, on earth as it is in heaven.
— Matthew 6:10

If it's what we pray for, it's what we should want and work for. So, how is it in heaven? We need imagination for that, something God gave us the capacity for. Most of us were best at it when we were children. Dependency, trust, and imagination: is this what it means to have child-like faith?
