Matthew 7:1 Judge not, that you be not judged. 2 For with what judgment you judge, you shall be judged: and with what measure you mete, it shall be measured to you again.
Our first passage warns us against judging others, for whenever, and wherever this is done personally to another, there is almost a guarantee that the one who judges is also at fault, and in some instances, it can disqualify persons from passing judgment since doing so will present a double standard.
However, our first passage is often misinterpreted or conflated, as applying broadly to persons drawing a conclusion based on their intelligence. In most cases we are born with the ability to think intelligently, or rationally, and because of this, we tend to draw our conclusions based on circumstantial evidences.
Gut feeling and whatever information we might pick up through our five senses also play a role as well as the news media and information highways, which in our day are heavily weighted with political, ethical, and Scriptural biases. Thus, it becomes even more difficult to judge correctly.
1st Samuel 1:14 And Eli said unto her, How long wilt thou be drunken? put away thy wine from thee. 15 And Hannah answered and said, No, my lord, I am a woman of a sorrowful spirit: I have drunk neither wine nor strong drink, but have poured out my soul before the Lord. 16 Count not thine handmaid for a daughter of Belial: for out of the abundance of my complaint and grief have I spoken hitherto.
May The Lord add His blessing to the study of His word. God bless!
