Matthew 7 English Standard Version
Judging Others
7 “Judge not, that you be not judged. 2 For with the judgment you pronounce you will be judged, and with the measure you use it will be measured to you. 3 Why do you see the speck that is in your brother’s eye, but do not notice the log that is in your own eye? 4 Or how can you say to your brother, ‘Let me take the speck out of your eye,’ when there is the log in your own eye? 5 You hypocrite, first take the log out of your own eye, and then you will see clearly to take the speck out of your brother’s eye.
Is it wise that we should operate on ourselves to remove obstacles to clear vision?
And he said to them, “Doubtless you will quote to me this proverb, ‘“Physician, heal yourself.”
While seeking the Proverb Jesus is referring to here the only thing I could find was Proverbs 4:20-22 (ESV)
20 My son, be attentive to my words;incline your ear to my sayings.
21 Let them not escape from your sight; keep them within your heart.
22 For they are life to those who find them, and healing to all their flesh.
Irony is quoting scripture to Jesus. This does however give us a method of having the Word of Truth do the surgery to remove any impediment in seeing the truth in any situation.
Judging a righteous judgment might be seen as allowing the Holy Spirit to tell us what Jesus has to say on any matter. If the scripture remains silent on the matter, perhaps we should also remain silent.
This boils down to His Word being embedded in our hearts.
The thing that is helpful to remember here is that the heart is not dependent on memory skills which decline in performance as we age.
And the peace of God, which surpasses all understanding, will guard your hearts and your minds in Christ Jesus.
We do not have to understand it to believe it. It is an issue of faith.
