Mark 15:33-35

And, about the ninth hour, Jesus cried out with a loud voice, saying:
"Eloi!, Eloi!, lama sabachthani?"
Which being interpreted means:
"My God!, My God!, Why hast Thou forsaken Me?"

In that terrible moment, God the Father turned away from God the Son.
Jesus experienced a literal Hell on Earth, as covered with the sin of all,
His Father turned away from Him and made Jesus a Perfect Sacrifice.

Jesus Christ experienced "Hell" so that mankind can experience Heaven.
