Timeamus, et amemus Deum vivum.https://www.youtube.com/watch?v=l1BTWCpEFRQ1453 The contrition called "imperfect" (or "attrition") is also a gift of God, a prompting of the Holy Spirit. It is born of the consideration of sin's ugliness or the
fear of eternal damnation and the other penalties threatening the sinner (contrition of fear). Such a stirring of conscience can initiate an interior process which, under the prompting of grace, will be brought to completion by sacramental absolution. By itself however, imperfect contrition cannot obtain the forgiveness of grave sins, but it disposes one to obtain forgiveness in the sacrament of Penance.
1041 The message of the Last Judgment calls men to conversion while God is still giving them "the acceptable time, . . . the day of salvation."629 It inspires a holy fear of God and commits them to the justice of the Kingdom of God. It proclaims the "blessed hope" of the Lord's return, when he will come "to be glorified in his saints, and to be marveled at in all who have believed."630
We must also point out the steps by which we may ascend to this divine virtue. The mercy of God first goes before us and converts our hearts to Him. This was the object of the Prophet's prayer: Convert us, O Lord, to thee, and we shall be converted. Illumined by this light the soul next tends to God by faith. He that cometh to God, says the Apostle, must believe that he is, and is a rewarder of them that seek him. A salutary fear of God's judgments follows, and the soul, contemplating the punishments that await sin, is recalled from the paths of vice. To this (state of soul) seem to refer these words of Isaias: As a woman with child, when she draweth near the time of her delivery, is in pain and crieth out in her pangs, so are we become. Then follows a hope of obtaining mercy from God, encouraged by which we resolve on improvement of life. Lastly, our hearts are inflamed by charity, whence springs that filial fear which good and dutiful children experience; and thus dreading only to offend the majesty of God in anything, we entirely abandon the ways of sin. - Roman Catechism
Besides, it was right that the just should be encouraged by the hope, the wicked appalled by the terror, of a future judgment; so that knowing the justice of God the former should not be disheartened, while the latter through fear and expectation of eternal punishment might be recalled from the paths of vice. Hence, speaking of the last day, our Lord and Saviour declares that a general judgment will one day take place, and He describes the signs of its approach, that seeing them, we may know that the end of the world is at hand. At His Ascension also, to console His Apostles, overwhelmed with grief at His departure, He sent Angels, who said to them: This Jesus who is taken up from you into heaven, shall so come, as you have seen him going into heaven - Ibid
