If He is omnipotent and perfectly loving, why not He saves ALL people in the history, from Adam until the last person?
Why does He want to make a Hell to burn unbelievers there?
You're not going to get an answer other than what He's revealed in Scripture: He is perfectly loving, Omnipotent, not all are saved, and Hell exists. As a believer, such things illustrate to my mind Who He Is and the riches of His Grace. In turn, I am moved to worship in awe, gratitude, and humility for granting me the gift of faith in His Son.
