What does Jesus say about your spirit going to heaven? I had an interesting question presented to me by a rector of a church.  He asked me to find anywhere in the bible where Jesus spoke of your spirit going to heaven and then research those specific passages (find the original documents and look at different translations).  While I thought about it for a while and then jumped in to do research, I found it not as easy I thought it would be. 

Where does Jesus speak specifically about the spirit?
Excellent question.  You're right, there doesn't seem to be a whole lot on the topic in Scripture, so I'm going to give this the best try I can.

Jesus seems to imply that his spirit will be with God the Father when he died. 

Luke 23:46:


  Jesus called out with a loud voice, “Father, into your hands I commit
  my spirit.” When he had said this, he breathed his last.


This seems to me to be an assumption that at least his spirit will be with God the Father.  We could then conclude from other passages in scripture, including those that indicate that Christ is the firstborn of all creation, and those in Romans 5 comparing and contrasting Christ to Adam, that our spirits will also be in heaven with Christ if we're found in Him. 

The only other area I could find directly from Jesus mouth is when he's talking to Nicodemus in John 3, and this is probably where the greatest evidence for spirits in heaven exists. 

John 3:5-6:


  Jesus answered, “Truly, truly, I say to you, unless one is born of
  water and the Spirit, he cannot enter the kingdom of God. That which
  is born of the flesh is flesh, and that which is born of the Spirit is
  spirit."


It seems like these two verses can be taken together to say that the Holy Spirit is the spiritual analogue to a human mother, and nobody can enter into the kingdom of God unless they are born of the Spirit, that is, unless they have a spirit.  Essentially, he seems to be saying that flesh doesn't enter into the Kingdom of God, but spirit does. 

Of course, accepting this interpretation depends on your view of the relationship between the Kingdom of God and the Kingdom of Heaven.
