1 Samuel 16:6-7
6 And it came to pass, when they were come, that he, (Samuel), looked on Eliab, and said, Surely the LORD'S anointed is before him.
7 But the LORD said unto Samuel, Look not on his countenance, or on the height of his stature; because I have refused him: for the LORD seeth not as man seeth; for man looketh on the outward appearance, but the LORD looketh on the heart.
When the prophet Samuel was to anoint the next king of Israel, (to replace the corrupted king Saul), his natural instinct approved of Eliab for the choice. But God had in mind Eliab's lowliest brother, David, the one everyone else neglected to even consider, leaving him in the field tending sheep. God explained His choice is based on other criteria, the heart on the inside.
8 For my thoughts are not your thoughts, neither are your ways my ways, saith the Lord.
9 For as the heavens are higher than the earth, so are my ways higher than your ways, and my thoughts than your thoughts.
God explains even further through the prophet Isaiah the His ways and thoughts are vastly different, vastly higher than those of humans, as high as outer space is above the land of Earth. This tells us that God has a vastly superior perspective of things and, from such, comes to vastly different conclusions about things.
And he (Jesus) said unto them (cultural elite, opinion makers, community leaders, the Pharisees), Ye are they which justify yourselves before men; but God knoweth your hearts: for that which is highly esteemed among men is abomination in the sight of God.
So Jesus explains that God's ways and thoughts are at odds with those of men. God values things very differently than humans do. God has a different value system than humans. God chooses things that humans reject.
This is why Jesus taught humans to, "Judge not!" because they are simply underqualified to judge correctly.
But humans make judgements all the time, anyways. Humans have their own system of judgments, a system of beliefs about right and wrong and a public mythology of heroes and villians, the famous and infamous of history. And their account of history itself is pulled in every direction by contesting interests of political groups of humans who seek to "control the narrative" from the first raw material of today's journalism to the final editions of higher education history text books - because they know that these carefully crafted legends are useful for justifying themselves, their agenda and manipulating the masses for their political purposes. In the end, none of is trustworthy. This can all be known by studying it earnestly enough. Humans and their histories contradict themselves to the point of forfeiting credibility.
But God's Word is trustworthy. This, too, can by known by studying it earnestly enough. The Bible exudes credibility sufficient of itself to convince of its own trustworthiness.
