The outer part of the tabernacle was the place where the Brazen altar and Laver were located. Being the outer side part of the Tabernacle.
In the outer part of the tabernacle, the priest that served and the children of Israel who brought their sacrifices to the tabernacle received their light from the natural planets (the sun in the day time and the moon and stars at night time).

In the outer court of the tabernacle, the relationship between God and the people was more focused on the repairing of the bad behaviors of the children of Israel.

The restraint from bad habits, the bringing of the sin offerings, the continues reminder of reminding the children of Israel that it is God who created the natural elements like the stars, the sun, the rain, their natural talents etc. 

And that they should not put their faith in the created things and forget the creator.

The outer part of the Tabernacle was designed to take the children of Israel from their own selfish bad habits (via the methods of sacrificing their animalistic desires), so that they may be able to obtain a deeper desire of entering into a deeper relationship with God.
