So that we can better examine the depths of our conscience, it would be ideal to first read several books on the Sacrament of Confession. Also, discuss any uncertainties that you may have with your wise Spiritual Father-Confessor. The greatest science or knowledge is to get to know ourselves. Also we must not deny ourselves the greatest thing that every human soul thirsts for: a peaceful conscience and eternity with God.
This joy is only granted by the God-Man, our Lord Jesus Christ. He himself instituted the single path to salvation for the repentant sinner within his Church, the holy Sacrament of Repentance and Confession. This is why, friend, you must overcome any obstacle whatsoever that blocks the road to Holy Confession. Here awaits you with genuine Christian love the good Confessor, the representative of Christ, who as a fellow human being can understand and have compassion on his brethren who are also sinful.
Cast far away, brethren, any thought of embarrassment or fright. Why be seared or frightened when your soul frets and pains from the deadly consequences of multi-faceted sin. If sickness tortured your body, would you avoid the hospital or doctor because of embarrassment? But at the same time, do not be led astray by certain people who wish to have read on them a “blessing only,” without having previously confessed. Whenever this happens from ignorance or neglect, it is a terrible sin and an insult to God. With faith, then, and honesty, proceed to Holy Confession.
Be certain also that the infinite love of the crucified and resurrected Lord will welcome you and transform you, removing the weight that burdens you! He himself said, “Come to Me all ye that are heavy laden and I will grant you rest.”

He who is accustomed to give account of his life at confession here will not fear to give an answer at the terrible judgment-seat of Christ. It is for this purpose that the mild tribunal of penitence was here instituted, in order that we, being cleansed and amended through penitence here below, may give an answer without shame at the terrible judgment-seat of Christ. This is the first motive for sincere confession, and, moreover, it must absolutely be made every year. The longer we remain without confessing, the worse it is for us, the more entangled we become in the bonds of sin, and therefore the more difficult it is to give an account. The second motive is tranquillity: the more sincere has been our confession, the more tranquil will the soul be afterwards. Sins are secret serpents, gnawing at the heart of a man and all his being; they do not let him rest, they continually suck his heart; sins are prickly thorns, constantly goring the soul; sins are spiritual darkness. Those who repent must bring forth the fruits of repentance.
Consciousness, memory, imagination, feeling, and will are helps to penitence. As we sin with all the powers of our soul, so penitence must be from our whole soul. Penitence in words only, without the intention of amendment and without the feeling of contrition, may be called hypocritical. Should the consciousness of sins be obscured, it must be cleared up; should the feeling be smothered and dulled, it must be roused; should the will become blunt and too weak for amendment, it must be forced; “the kingdom of heaven suffereth violence, and the violent take it by force.” (St. Matt. 11:12) Confession must be sincere, deep, and full.
