Jesus made it clear, in His absence they would experience a great Loss. The Helper from Heaven would come to them and represent the character and purposes of Jesus, just as the Holy Spirit was there for Christ, teaching Him of His Heavenly Father.
The Spirit represents Jesus to each individual without the limitations of time and space Jesus had. Bringing all the authority and love and tenderness and power of God to us personally. Only By the Holy Spirit can we resist the power of sin rolling down through every generation in our sinful nature. By these promises we are partakers of Divine nature having escaped the corruption that is in the world through lust.
the oil of anointing that flowed down the robe of Aaron represented the Holy Spirit that enveloped Jesus at his inauguration as High priest and flowed down to earth through His great sacrifice and victory in a great torrent, to bring us heaven, to lift us up and restore our communion with heaven.
The white curtain wall around the desert sanctuary surrounded the work of Christ on earth and in heaven. From the alter of sacrifice to the Most Holy Place Christ walked from earth to heaven. Earth is profoundly connected to heaven by the powerful working of the Holy Spirit. The Spirit makes known the head of the human race, by creation and now also by incarnation, death, resurrection, and intercession is Jesus. The very heart of God is pouring love and mercy on the world.
