The spirit world in scripture

We live in a spirit world and a physical world. Each world has multiple regions, structures, atmospheres and purposes. Our souls primarily live and thrive in the physical world and our spirits live and thrive in the spirit world.
God intends for our spirits to lead our souls in both worlds!
The human spirit relates to the spirit world and the soul follows
“What no eye has seen, what no ear has heard, and what no human mind has conceived” — the things God has prepared for those who love him— these are the things God has revealed to us by his Spirit.
The Spirit searches all things, even the deep things of God. For who knows a person’s thoughts except their own spirit within them? In the same way no one knows the thoughts of God except the Spirit of God. What we have received is not the spirit of the world, but the Spirit who is from God, so that we may understand what God has freely given us. This is what we speak, not in words taught us by human wisdom but in words taught by the Spirit, explaining spiritual realities with Spirit-taught words. ...

"The Spirit himself doth testify with our spirit, that we are children of God." Romans 8:16
