Humility is the only virtue that no devil can imitate. If pride made demons out of angels, there is no doubt that humility could make angels out of demons.
John ClimacusDo not make judgments, and you will travel no quicker road to the forgiveness of your sins. 'Judge not, so that you may not be judged' (Lk. 6:37).
John ClimacusForgetting offences is a sign of sincere repentance. If you keep the memory of them, you may believe you have repented but you are like someone running in his sleep. Let no one consider it a minor defect, this darkness that often clouds the eyes even of spiritual people.
John ClimacusOur inhuman enemy inspires the thought that God loves mankind, and that He quickly forgives this sin. But when we observe the guile of demons, then we see that after the commission of the sin, they suggest to us that God is a righteous and implacable Judge. The first they say in order to lead us to sin, the second, in order to weigh us down in despair.
