Because God's justice is inexorable, it is hard to obtain forgiveness for sins committed with complete deliberation.

It is harmful to remember previous sins in detail. For if they bring you sorrow, they will estrange you from hope, but if they are remembered without sorrow, they will introduce the previous defilement. If you want to bring to God an uncondemned confession, then don't remember your sins in detail, but manfully endure the suffering that is coming because of them.

Whoever with fear of God corrects and directs a sinner gains virtue for himself, that of opposition to sin. But whoever insults a sinner with rancor and without good will falls, according to a spiritual law, into the same passion with the sinner.

If someone falls into any sin and is not sincerely grieved about it, it is easy for him to fall into the same thing again.

A man who hates the passion cuts off their causes. But a man who remains among their causes experiences even against his will the conflict from the passions. It is not possible to be mentally inclined toward a passion if one does not love its cause. For who, disdaining shame, is given to vainglory? Or who, loving lowliness, is bothered by dishonor? Who, having a broken and humble heart, accepts fleshly sweetness? Or who, believing in Christ, is concerned about temporal things, or argues about them?

The devil makes small sins seem smaller in our eyes, for otherwise he can't lead us to greater evil.

Whoever prays for those who hurt him lays the demons low; but he who opposes his affronter is bound to the demons.
