Why do you notice the splinter in your brother’s eye, but do not perceive the wooden beam in your own eye? How can you say to your brother, ‘Let me remove that splinter from your eye,’ while the wooden beam is in your eye? You hypocrite, remove the wooden beam from your eye first; then you will see clearly to remove the splinter from your brother’s eye. MT 7:3-5
Don’t sin any more
Then the scribes and the Pharisees brought a woman who had been caught in adultery and made her stand in the middle. They said to him, “Teacher, this woman was caught in the very act of committing adultery. Now in the law, Moses commanded us to stone such women. So what do you say?” They said this to test him, so that they could have some charge to bring against him. Jesus bent down and began to write on the ground with his finger. But when they continued asking him, he straightened up and said to them, “Let the one among you who is without sin be the first to throw a stone at her.” Again he bent down and wrote on the ground. And in response, they went away one by one, beginning with the elders. So he was left alone with the woman before him. Then Jesus straightened up and said to her, “Woman, where are they? Has no one condemned you?” She replied, “No one, sir.” Then Jesus said, “Neither do I condemn you. Go, [and] from now on do not sin any more.” John 8:3-11
Jesus is stronger than Satan
They came to the other side of the sea, to the territory of the Gerasenes. When he got out of the boat, at once a man from the tombs who had an unclean spirit met him. The man had been dwelling among the tombs, and no one could restrain him any longer, even with a chain. In fact, he had frequently been bound with shackles and chains, but the chains had been pulled apart by him and the shackles smashed, and no one was strong enough to subdue him. Night and day among the tombs and on the hillsides he was always crying out and bruising himself with stones. Catching sight of Jesus from a distance, he ran up and prostrated himself before him, crying out in a loud voice, “What have you to do with me, Jesus, Son of the Most High God? I adjure you by God, do not torment me!” (He had been saying to him, “Unclean spirit, come out of the man!”) He asked him, “What is your name?” He replied, “Legion is my name. There are many of us.” And he pleaded earnestly with him not to drive them away from that territory. Now a large herd of swine was feeding there on the hillside. And they pleaded with him, “Send us into the swine. Let us enter them.” And he let them, and the unclean spirits came out and entered the swine. The herd of about two thousand rushed down a steep bank into the sea, where they were drowned. As he was getting into the boat, the man who had been possessed pleaded to remain with him. But he would not permit him but told him instead, “Go home to your family and announce to them all that the Lord in his pity has done for you.” Then the man went off and began to proclaim in the Decapolis what Jesus had done for him; and all were amazed. Mark 5:1-13. 18-20
How to win the battle against sin?
At the turn of the year, the time when kings go to war, David sent out Joab along with his officers and all Israel, and they laid waste the Ammonites and besieged Rabbah. David himself remained in Jerusalem. One evening David rose from his bed and strolled about on the roof of the king’s house. From the roof he saw a woman bathing; she was very beautiful. David sent people to inquire about the woman and was told, “She is Bathsheba, daughter of Eliam, and wife of Uriah the Hittite, Joab’s armor-bearer.” Then David sent messengers and took her. When she came to him, he took her to bed, at a time when she was just purified after her period; and she returned to her house. But the woman had become pregnant; she sent a message to inform David, “I am pregnant.” So David sent a message to Joab, “Send me Uriah the Hittite.” Joab sent Uriah to David. And when he came, David asked him how Joab was, how the army was, and how the war was going, and Uriah answered that all was well. David then said to Uriah, “Go down to your house and bathe your feet.” Uriah left the king’s house, and a portion from the king’s table was sent after him. But Uriah slept at the entrance of the king’s house with the other officers of his lord, and did not go down to his own house. David was told, “Uriah has not gone down to his house. David summoned him, and he ate and drank with David, who got him drunk. But in the evening he went out to sleep on his bed among his lord’s servants, and did not go down to his house. The next morning David wrote a letter to Joab which he sent by Uriah. This is what he wrote in the letter: “Place Uriah up front, where the fighting is fierce. Then pull back and leave him to be struck down dead.” So while Joab was besieging the city, he assigned Uriah to a place where he knew the defenders were strong. When the men of the city made a sortie against Joab, some officers of David’s army fell, and Uriah the Hittite also died. 2 Sm 11, 10a. 13-17
God's children
Children, let no one deceive you. The person who acts in righteousness is righteous, just as he is righteous. Whoever sins belongs to the devil, because the devil has sinned from the beginning. Indeed, the Son of God was revealed to destroy the works of the devil. No one who is begotten by God commits sin, because God’s seed remains in him; he cannot sin because he is begotten by God. In this way, the children of God and the children of the devil are made plain; no one who fails to act in righteousness belongs to God, nor anyone who does not love his brother. 1 John 3:7-10
