Is the Holy Ghost the second comforter?

During elders quorum today, the instructor commented that Jesus is the Second Comforter. It seemed a bit odd to me, but the Bible Dictionary supports this idea.

It seems at odds with a couple of other scriptures. Consider John 14:16:

I will pray the Father, and he shall give you another Comforter

If the first comforter is the Holy Ghost, why does Jesus refer to him as another comforter? Another implies that a comforter already existed.

How do we reconcile this apparent discrepancy?

 

Ministering to the lower kingdoms of glory

In Gospel Doctrine class today, we were discussing the kingdoms of glory, and at one point we read D&C 76:86–88:

These are they who receive not of his fulness in the eternal world, but of the Holy Spirit through the ministration of the terrestrial; and the terrestrial through the ministration of the celestial. And also the telestial receive it of the administering of angels who are appointed to minister for them, or who are appointed to be ministering spirits for them; for they shall be heirs of salvation.

While the conversation continued on discussing the checklists necessary to get into each question, I sat there pondering these three verses.

Am I to understand that people in the terrestrial world will minister to people in the telestial world and those in the celestial will minister to those in the terrestrial?

If you look at the footnote in verse 87, you will see it points to D&C 138:37:

That they might carry the message of redemption unto all the dead, unto whom he could not go personally, because of their rebellion and transgression, that they through the ministration of his servants might also hear his words.

It seems that D&C 76:86–88 is referring to people from the higher kingdoms ministering to the lower kingdoms. So, my next question is why?

Why does anyone in the kingdoms need ministering? It seems to be a common belief in the church that once you’re assigned to a kingdom, you will remain there forever. If this is true, what purpose would it serve to be taught the gospel? After all, we received a chance in the Spirit World to accept the gospel.

On the surface, this seems like a pointless exercise. On the other hand, perhaps we’re missing something. What do you think?
