There is an apparition of Our Lady at Garabandal that talks about The Great Warning and Illumination of Conscience at the end of time. According to the Marian apparition, the Great Warning is the illumination of conscience that comes shortly before the end times and everyone will personally experience an awareness of their own sinfulness. The person will be alone before God and that will be a kind of “wake-up call” to each human being. While this may sound intimidating, we should all be living our lives with a knowledge of our sinfulness and a constant effort to remedy our faults.
The End Times: The Great Warning And Illumination Of Conscience
What can we expect during the end times? Illumination conscience, the end times signs, Marian apparitions? No one knows the day or hour that Jesus will come again, the second coming is a mystery to everyone. We should be preparing each day for the coming of Christ. Prayer, examination of conscience, frequent reception of the sacraments, reading scripture, all of these things help us to prepare for the end of time. The Great Warning is not something to be feared, we will see our sinfulness before God and then work on purifying ourselves, this is something we should be doing each day.
What Does The Catechism Of The Catholic Church Say About The End Times?
The Church’s ultimate trial
675 Before Christ’s second coming the Church must pass through a final trial that will shake the faith of many believers.574 The persecution that accompanies her pilgrimage on earth575 will unveil the “mystery of iniquity” in the form of a religious deception offering men an apparent solution to their problems at the price of apostasy from the truth. The supreme religious deception is that of the Antichrist, a pseudo-messianism by which man glorifies himself in place of God and of his Messiah come in the flesh.576
676 The Antichrist’s deception already begins to take shape in the world every time the claim is made to realize within history that messianic hope which can only be realized beyond history through the eschatological judgment. The Church has rejected even modified forms of this falsification of the kingdom to come under the name of millenarianism,577 especially the “intrinsically perverse” political form of a secular messianism.578
677 The Church will enter the glory of the kingdom only through this final Passover, when she will follow her Lord in his death and Resurrection.579 The kingdom will be fulfilled, then, not by a historic triumph of the Church through a progressive ascendancy, but only by God’s victory over the final unleashing of evil, which will cause his Bride to come down from heaven.580 God’s triumph over the revolt of evil will take the form of the Last Judgment after the final cosmic upheaval of this passing world.581
* II. TO JUDGE THE LIVING AND THE DEAD
678 Following in the steps of the prophets and John the Baptist, Jesus announced the judgment of the Last Day in his preaching.582 Then will the conduct of each one and the secrets of hearts be brought to light.583 Then will the culpable unbelief that counted the offer of God’s grace as nothing be condemned.584 Our attitude to our neighbor will disclose acceptance or refusal of grace and divine love.585 On the Last Day Jesus will say: “Truly I say to you, as you did it to one of the least of these my brethren, you did it to me.”586
679 Christ is Lord of eternal life. Full right to pass definitive judgment on the works and hearts of men belongs to him as redeemer of the world. He “acquired” this right by his cross. The Father has given “all judgment to the Son”.587 Yet the Son did not come to judge, but to save and to give the life he has in himself.588 By rejecting grace in this life, one already judges oneself, receives according to one’s works, and can even condemn oneself for all eternity by rejecting the Spirit of love.Catechism of the Catholic Church
