Our Lady in Medjugorje tells you how to act with those who have sinned

Message dated February 4, 1986
When you realize that a person has committed a sin, do not tell him immediately that he was wrong, but kneel before the cross and pray for him. In fact, since that person has a wound in the heart, he or she could not immediately understand your words and could not feel your love. Therefore it is necessary to pray for her to repent and recognize her sin before God.
Some passages from the Bible that can help us understand this message.
Gn 3,1-13
The snake was the most cunning of all the wild beasts made by the Lord God. He said to the woman: "Is it true that God said: You must not eat of any tree in the garden?". The woman replied to the snake: "Of the fruits of the trees in the garden we can eat, but of the fruit of the tree that stands in the middle of the garden God said: You must not eat and touch it, otherwise you will die." But the snake said to the woman: “You will not die at all! Indeed, God knows that when you eat them, your eyes would open and you would become like God, knowing the good and the bad ". Then the woman saw that the tree was good to eat, pleasing to the eye and desirable to acquire wisdom; she took some fruit and ate it, then also gave it to her husband, who was with her, and he also ate it. Then both of them opened their eyes and realized they were naked; they braided fig leaves and made themselves belts. Then they heard the Lord God walking in the garden in the breeze of the day and the man and his wife hid from the Lord God in the middle of the trees in the garden. But the Lord God called the man and said to him, "Where are you?". He replied: "I heard your step in the garden: I was afraid, because I am naked, and I hid myself." He went on: “Who let you know you were naked? Have you eaten from the tree of which I commanded you not to eat? ". The man replied: "The woman you placed beside me gave me a tree and I ate it." The Lord God said to the woman, "What have you done?". The woman replied: "The snake has deceived me and I have eaten."
Tobias 12,8-12
Good thing is prayer with fasting and almsgiving with justice. Better the little with justice than wealth with injustice. It is better to give alms than to put aside gold. Begging saves from death and purifies from all sin. Those who give alms will enjoy long life. Those who commit sin and injustice are enemies of their lives. I want to show you the whole truth, without hiding anything: I have already taught you that it is good to hide the king's secret, while it is glorious to reveal the works of God. Know therefore that, when you and Sara were in prayer, I would present the witness of your prayer before the glory of the Lord. So even when you buried the dead.
