The Son of God spokes: "See how I died for love, yet nobody repays me with love, but they take from me what is justly mine. It would be just if people improved their lives in proportion to the efforts it cost to redeem them. Now, however, people want to live all the worse in proportion to the pain I suffered in redeeming them. The more I show them how abominable their sin is, the more boldly they want to sin. Look, therefore, and consider how it is not without cause that I am angry: They manage to change for themselves my good will into anger. I redeemed them from sin, and they get themselves increasingly entangled in sin. So, my child, give me what you are obliged to give me, I mean, keep your soul clean
[1] for me, because I died for it in order that you might keep it clean for me."
[1]. "So then, dear friends, since you are looking forward to this, make every effort to be found spotless, blameless and at peace with him." cf. (2 Peter 3:14)
