We consider an evil great in proportion to the length of time we have to bear it. To be blind is certainly a misfortune; but it is a greater misfortune to be blind for our whole life than for one day. Sin, therefore, is the greatest of all evils; because the misfortune it brings upon us lasts not merely for a great many years, but for all eternity. Even slight sufferings would be terrible if they lasted forever, but the sufferings for mortal sin are worse than we can describe or imagine, and they are forever. The greatest evils in this world will not last forever, and are small when compared with sin. Sin makes us ungrateful to God, who gives us our existence. "Our Preserver," because if God ceased to watch over us and provide for us, even for a short time, we would cease to exist. "Our Redeemer," who suffered so much for us. *202 Q. How many kinds of contrition are there? A. There are two kinds of contrition: perfect contrition and imperfect contrition. *203 Q. What is perfect contrition? A. Perfect contrition is that which fills us with sorrow and hatred for sin because it offends God, who is infinitely good in Himself and worthy of all love. It can be a very hard thing to have perfect contrition, but we should always try to have it, so that our contrition may be as perfect as possible. This perfect contrition is the kind of contrition we must have if our mortal sins are to be forgiven if we are in danger of death and cannot go to confession. Imperfect contrition with the priest's absolution will blot out our mortal sins. *204 Q. What is imperfect contrition? A. Imperfect contrition is that by which we hate what offends God because by it we lose Heaven and deserve Hell; or because sin is so hateful in itself. *205 Q. Is imperfect contrition sufficient for a worthy confession? A. Imperfect contrition is sufficient for a worthy confession, but we should endeavor to have perfect contrition. 206 Q. What do you mean by a firm purpose of sinning no more? A. By a firm purpose of sinning no more I mean a fixed resolve not only to avoid all mortal sin, but also its near occasions. "Fixed." Not for a certain time, but for all the future. 207 Q. What do you mean by the near occasions of sin? A. By the near occasions of sin I mean all the persons, places and things that may easily lead us into sin.
