The Illumination is an astounding event in which God will illuminate the conscience of every person, who will momentarily see the state of his soul through God’s eyes.
The Illumination is a Grace to give us an opportunity to clean our souls. We will observe our whole life, words and deeds, good and bad thoughts, and we will feel the repercussions of every act or omission on us, other persons and God. The saints have said many sinners will repent of their sins and be saved.
The Warning will come from God and will be visible worldwide for everyone. First, a miraculous worldwide warning will happen in the sky to purify us — Roman Catholics should prepare for the Illumination through the sacrament of Penance.
The next two biblical verses discuss the Illumination of Conscience.
“Then I will draw near to you for judgment. I will be a swift witness against the sorcerers, against the adulterers, against those who swear falsely, against those who oppress the hired worker in his wages, the widow and the fatherless, against those who thrust aside the sojourner, and do not fear me, says the Lord of hosts.” (Malachi 3:5)
“Many shall be refined, purified, and tested, but the wicked shall prove wicked; the wicked shall have no understanding, but those with insight shall.” (Daniel 12:10)
