When what you say is wrong. I will counter it.
Yes, Jesus left. Yes He will return. But, as God He isn't bound by space and time. He is here even now. You can't get away from him. He isn't on some planet someplace. He is right here.
Whither shall I go from thy spirit? or whither shall I flee from thy presence? If I ascend into heaven, thou art there: if I make my bed in hell, behold, thou art there. If I take the wings of the morning, and dwell in the uttermost parts of the sea; even there shall thy hand lead me, and thy right hand shall hold me" (Psalms 139:7-10).
And lo, I am with you alway, even to the end of the world" (Matthew 28:18).
"Heaven is my throne, and earth is my footstool. Where is the house that you will build Me? And where is the place of My rest?" (Isaiah 66:1).
Yea, though I walk through the valley of the shadow of death, I will fear no evil: for thou art with me; thy rod and thy staff they comfort me" (Psalms 23:4).
"Because He is at my right hand, I shall not be moved" (Psalms 16:8).
When thou passest through the waters, I will be with thee; and through the rivers, they shall not overflow thee...For I am the Lord thy God, the Holy One of Israel..." (Isaiah 43:2,3).
So YES. Jesus left and will return again some day. But, as God, He is here with us now. His return will be physical. Yet His presence is here even now.
The ministering aspect of the Holy Spirit is what is active on earth right now. Jesus "withdrew" Himself in order that the Spirit might minister. Does not mean that Jesus as God went away. God doesn't leave us. He doesn't forsake us. He is a prayer away as they say, and not even that. He's with us when we can't even pray.
Jesus specifically told us that He would be with us even to the very end of the age.
