In the wake of a political miracle, Israel arrived back in their land. There was so much to do: houses to build, a temple to rebuild, a city to renovate, food to be grown and borders to protect.
But first they worshipped.
They knew that regular worship would define them, shape them, remind them of their identity. It still does.
It might not be a perfect experience, but it is the most important thing that the returning church must do.
