The vision of Jesus among the lampstands is different than the Carpenter-Teacher because Jesus was both fully God and fully man. While He was teaching on this Earth, He showed his physical body. Through this, He showed us the path to righteousness and taught that it is possible to live a more and pleasing way. Because He is now re-united in Heaven, He shows His Spirit body.
Emotionally, the reader should sense by this vision the Holiness, purity and cleanness of God and have a sense of intense reverance for who He is.
This understanding of Jesus is important to a balanced faith because Jesus is God, and we were made in "their" image. We are cleansed and seen as righteous by our faith and belief in who He was, is , and will always be.
He walked among us, suffered, and died - just like we do.
Because of this, and because He rose again, we build our faith by knowing the promise. He died and rose as was promised and therefore we also will obtain a spirit body and be cleansed in Heaven to share eternal companionship with the Father.
