Let's start with the simple details:
1. Our essence is a "soul" and that is a dimension that is not measurable by the physical world
2. The body is only a tool in this world (this physical lower world, there are "other higher worlds or kingdoms")
3. The reason the body and soul are mixed in this world is for us to refined by the challenges the "flesh" brings and for us to have a higher level of service due too having a challenge (i.e. resistance makes someone much better and able to grow....count it all blessings for trials and tribulations")
4. You have to know when the Bible is using "metaphors". Yes clearly the Almighty G-d does not have hands and eyes, but because we cannot understand G-d at all, not even a tiny little percent of His Whole Essence, He is like a good Father who "simplifies" things for us to understand in bit size form.
5. The "right side of G-d" signifies Mercy and the left side is judgment.
With this all put together, Jesus, Messiah is a very very high-level soul, spirit, angel (etc) and I do not know exactly where He is, but in the higher worlds, He is constantly preparing the way for our arrival and fighting tooth and nail every sin that comes our way. He is also on the right side of G-d to ask for mercy on us sinners. That is what is meant by being on the "right side".
