To many times men think it is a contest like in this story.
Luke 18:
The Parable of the Pharisee and the Tax Collector
9 To some who were confident of their own righteousness and looked down on everyone else, Jesus told this parable: 10 “Two men went up to the temple to pray, one a Pharisee and the other a tax collector. 11 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. 12 I fast twice a week and give a tenth of all I get.’
13 “But the tax collector stood at a distance. He would not even look up to heaven, but beat his breast and said, ‘God, have mercy on me, a sinner.’
14 “I tell you that this man, rather than the other, went home justified before God. For all those who exalt themselves will be humbled, and those who humble themselves will be exalted.”
I really do believe Jesus was talking about cutting off hand He was talking about doing the extreme to get rid of sin in our own life.
In my own experience men try to put others down to make their own self seem better and that the only way to make changes around us is to start with ourselves. When we try to force changes in other peoples life especially with a plank in our own eye, they are going to make changes by getter rid of you in their life.
I dated a girl that was self-righteous a long time ago. It was like trying to walk on egg shells didn't know when I was going to do something wrong and be corrected, I didn't like it especially with her obvious flaws.
I couldn't force her to change and even pointed to her the self-righteousness, even with scripture. I simple said I think this relationship isn't going to work that I am a weaker and I am causing her to stumble and ended the relationship.
