Where do you want to be when you die? What would you like your last words to be? Many saints and holy men died saying edifying words, Venerable Augustine Baker of the blessed sacrament died after singing the Salve Regina, Charlemegne is recounted as saying "Lord into Thy hands I commend my spirit." Perhaps you might want to die in the arms of your wife like St. Nicholas Von Flue, or like a penitent thief.
Would you want to die singing the song "Kiss the Devil"? A song that chorus actually says "I will love the devil and sing his song". In fact there is not any substance to it, it almost reads as a satanic parody of the Divine Praises. That was the song that apparently the band Eagles of Death metal started performing according to the Daily Mail when the gunmen showed up and starting their killing spree.
"For yourselves know perfectly, that the day of the Lord shall so come, as a thief in the night." 1 Thessalonians 5:2 . Consider what you listen to, consider what you do, consider where you go. Our time is very limited, let us redeem it, because the awful day of judgement awaits when we leave these frail bodies, and every idle word shall be judged. If you listen to such music, or go to such places repent. Pray for Paris, but forget not the need to make reparation to Christ, not just for those who take innocent life, but for those who mock Him, Hate him, and blaspheme Him. God have mercy on us.
