Building the Tabernacle

As I build up to a capital campaign in the next few weeks, I am looking at the building of the tabernacle and the temple in the Old Testament.  What were their purposes?  Why was it important that the people give to help them be built? For this sermon, I built a replica of the Ark of the Covenant and rearranged furniture in the sanctuary to be more accurate to the set up of the tabernacle.  I walk around a lot, so I had to have my phone set on the first pew to record.
