Moses wanted to see the tabernacle built. 

He knew that he would need willingness and wisdom for it to become reality.
He needed for the people that had the supplies to willingly give of them.
He needed for the people that had the talent to build to use their wisdom to see the project completed.
He knew without one he couldn’t have the other. The tabernacle would never be completed.
Today we look to build up a different type of tabernacle. We look to win people over to Jesus, converting them into temples of the Holy Spirit. 
Just as there was diversity within the Israelite people there are many differing roles within the church: Preachers, teachers, prayer warriors, builders, visionaries, encouragers, givers, etc.
To be successful in building the kingdom of God two things are still required of his people: willingness to submit and wisdom to grow.
