This article published by Aleteia on hell’s secrets revealed by one of the Church’s chief exorcists, Father Gabriel Amorth, is interesting because it begins to put in order the Christian belief in God, and His opponent, Lucifer (Satan, or Devil) and creation of hell.
I recommend reading the article if nothing else your awareness is heightened and you begin to take seriously the place of sin, evil and hell in this life. The Lord Himself has revealed the extent of evil; the saints have spoken of evil and we ought to pay and pray for the gifts of the Holy Spirit, especially Wisdom, courage and fortitude. Many people think of hell and the devil as quaint stories to scare people into submission to Church authority. I assure you, hell is real and people have elected to take up residence there thus rejecting God.
Advice given in the article: “To be a man of faith and prayer and always to ask the intercession of Mary Most Holy. And then always to be humble…”
