32“If you love those who love you, what credit is that to you? For even sinners love those who love them. 33If you do good to those who do good to you, what credit is that to you? For even sinners do the same. 34If you lend to those from whom you hope to receive, what credit is that to you? Even sinners lend to sinners, to receive as much again. 35But love your enemies, do good, and lend, expecting nothing in return. Your reward will be great, and you will be children of the Most High; for he is kind to the ungrateful and the wicked. 36Be merciful, just as your Father is merciful. 37“Do not judge, and you will not be judged; do not condemn, and you will not be condemned. Forgive, and you will be forgiven; 38give, and it will be given to you. A good measure, pressed down, shaken together, running over, will be put into your lap; for the measure you give will be the measure you get back.” 39He also told them a parable: “Can a blind person guide a blind person? Will not both fall into a pit? 40A disciple is not above the teacher, but everyone who is fully qualified will be like the teacher. 41Why do you see the speck in your neighbor’s eye, but do not notice the log in your own eye? 42Or how can you say to your neighbor, ‘Friend, let me take out the speck in your eye,’ when you yourself do not see the log in your own eye? You hypocrite, first take the log out of your own eye, and then you will see clearly to take the speck out of your neighbor’s eye. (Luke 6:32-42, NRSV)
Why do we focus on others sins and not our own? It is easy to see what is wrong with someone else and point it out. It is so much easier to bring others down because of their faults than to work on ourselves.
Once we get our own lives together then we can point out others faults which will be never. The only one who can set out lives straight is God and only if we will follow after God.
Look at your own faults and repent of your weaknesses to God and allow God to make you perfect as only God can.
