Nehemiah 13 is the last chapter of the book. They have finished their major building project, but now the people have fallen back into some of their problems from the past. Nehemiah has to "call them out" and "call them back" to God. After this corona virus situations passes, what happens if we just go back to the problems we had in the past? We happens if we don't carry forward any of the lessons we have learned during this time? That happens a lot. We need to develop habits and routines to keep us growing in our faith in Christ that won't come to an end, but will continue forward.
