John 14:28. 28 Ye have heard how I said unto you, I go away, and come again unto you. If ye loved me, ye would rejoice, because I said, I go unto the Father: for my Father is greater than I.

At times Holy Spirit refers to the Father and at times it refers to the Son. In this passage we see it refers to the Son. Both the Father and the Son are spirits. They are spirits of the same essence as the Son was taken out of (begotten by) the Father without hands.

We are spirits driving meat suits. Christ was a holy spirit driving a meat suit. When He's not driving a meat suit He is here in holy spirit form.

It's clear from John 14:28 that Christ was speaking of Himself in the third person in 14:26.
