saint is a sinner ...

Saint is a sinner, conscious of his weaknesses ...

Holy man is not a sinless person. The saint is aware of his sins, is fighting with them, is in pain because of his sins, he is struggling and when falling arises all over again, counting only on God's mercy.

"Have mercy on me, O God, according to your unfailing love; according to your great compassion blot out my transgressions. Wash away all my iniquity and cleanse me from my sin.

For I know my transgressions, and my sin is always before me.

Against you, you only, have I sinned and done what is evil in your sight; so you are right in your verdict and justified when you judge.

Surely I was sinful at birth, sinful from the time my mother conceived me. Yet you desired faithfulness even in the womb; you taught me wisdom in that secret place.

Cleanse me with hyssop, and I will be clean; wash me, and I will be whiter than snow. Let me hear joy and gladness; let the bones you have crushed rejoice. Hide your face from my sins and blot out all my iniquity. (Psalm 50[51]:1-9)

Sinless and "saintly" are only the Pharisees ...

 "Two men went up to the temple to pray, one a Pharisee and the other a tax collector. The Pharisee stood by himself and prayed: 'God, I thank you that I am not like other people—robbers, evildoers, adulterers—or even like this tax collector. I fast twice a week and give a tenth of all I get.'" (Luck 18:10-12)
