It's one thing to be sorry for our sins out of fear of hell, it's quite another to be sorry for having offended God, who is All-Good and deserving of our love.
Perfect contrition comes when we have a close and loving relationship with God.
When our mind and heart meditates upon the agony suffered by Jesus for the sake of our salvation, we begin to sincerely detest our sins because they offend God, who is deserving of all our love.
Our salvation was not easy. It cost Our Lord his life. He gave himself completely.
Our savior was slandered, beaten, scourged, mocked spat upon and humiliated before jeering crowds. His sacred head, crowned with pain; his hands and feet pierced with iron nails; his entire body crushed with pain on account of our sins.
"But he was pierced for our transgressions, he was crushed for our iniquities; the punishment that brought us peace was on him, and by his wounds we are healed."
-- Isaiah 53:5
"Those who belong to Christ Jesus have crucified the flesh with its passions and desires. If we live by the Spirit, let us also keep in step with the Spirit." -Galatians 5:24-25
Short Audio Talks by Archbishop Fulton J. Sheen:
We were made for God. The purpose of the intellect is Truth: God is Truth itself. The purpose of the human will is Goodness and Love: God is Goodness and Love itself.
Sin is the misuse of our intellect and will. When we bring sin into the world we hurt ourselves and our neighbor. We are made in the image and likeness of God. When we choose to sin, we offend God and destroy our peace.
Through the spectacle of the crucifixion God shows us the horror of sin, and His love for us as he took upon himself the sins of the world.Meditating on the sufferings of Christ is a means for the human heart to be enticed into sorrow and repentance of sin, leading to a sincere conversion of heart.
