Heaven
The creatures and people of the Heavenly realm.
God the Father (God)
God the Son (Jesus)
Fully God, yet fully man. This is the dude that allowed himself to be beaten, spit at, mocked, and killed in the most horrific manner imaginable to humankind (being crucified) just to save us. Doesn't that just make you feel all warm and fuzzy inside?
God the Holy Spirit/Ghost
I know this may seem weird, but all three Gods are actually one God. The way many people think about it is like an apple, the skin, the core, and the flesh. Three parts, one apple. One God. Get it?
