How can a loving and all-knowing God allow anyone to spend eternity in hell?

God has clearly revealed His character, His desires, and His promises through the Bible. We all need to decide what our baseline is for identifying truth.

2 Peter 1:20-21 says, “Above all, you must realize that no prophecy in Scripture ever came from the prophet’s own understanding, or from human initiative. No, those prophets were moved by the Holy Spirit, and they spoke from God.”

Romans 1:18-21 says, “God shows his anger from heaven against all sinful, wicked people who suppress the truth by their wickedness. They know the truth about God because he has made it obvious to them. For ever since the world was created, people have seen the earth and sky. Through everything God made, they can clearly see his invisible qualities—his eternal power and divine nature. So they have no excuse for not knowing God. Yes, they knew God, but they wouldn’t worship him as God or even give him thanks. And they began to think up foolish ideas of what God was like. As a result, their minds became dark and confused.”

If Scripture is true, it would be wise to choose a Biblical frame-of-reference in all our decision making, especially where we will spend eternity!
