Jesus is speaking about the Father. There is a false idea that God changes from one form to another. In this false idea, The Father becomes the Son and then the Holy Spirit and back again. The Bible is clear this is wrong! There are three distinct persons in the Trinity. Jesus is going to be with the Father and they will be there together. It is a good thing for us that Jesus has left. It means that His work is finished and salvation is here in Him.
