Mary K Baxter was taken by the Lord Jesus Christ to visit Hell and later, Heaven. This is a paraphrased account of what she saw as she and Jesus stood at the precipice of the pit of hell.

They heard a cry from the first pit and saw a soul like a skeleton, crying, “Jesus, have mercy!”
It was the voice of a woman. When she saw her she wanted pull her out of the fire for the sight broke her heart. Decayed flesh hung by shreds from her bones and as it burned, it fell off into the bottom of the pit and her eyes were now only empty sockets and the woman had no hair. The fire started at her feet in small flames and grew as it climbed up and over her body. The woman seemed to be constantly burning, even when the flames were only embers. From deep down inside her came cries and groans of despair, “Lord, Lord, I want out of here!”
She tried reaching out to Jesus. Mary K. looked at Jesus, where she saw great sorrow on His face. Jesus told Mary K, “My child, you are here with Me to let the world know that sin results in death, that hell is real. “
When Mary K. looked at the woman again, worms were crawling out of her skeleton and were not destroyed by the fire. Jesus said, “She knows and feels those worms inside.”
The fire reached its peak and the horrible burning started all over again. Great cries and deep sobs shook the form of this woman-soul. She was lost and there was no way out.

Note: There are even many more vivid accounts of what Mary K. Baxter saw as Jesus and she journeyed through Hell
