John 2:25

And needed not that any should testify of man: for he knew what was in man.

There was no need for Jesus to be educated about human nature or the opinions of others. Regardless of who He spoke with, He knew exactly what each person needed to hear and what they needed to know. Hence, verse 24 indicates that He did not trust all those who claimed to follow Him in Jerusalem. Throughout history, Jesus has proven to be able to reach people at the exact moment they need it.
As the psalmist reminds us, God knows each of us deeply. The Lord knows when we sit down and when we rise up. Despite being far away, he is aware of our thoughts. Our paths are scrutinized by Him since He knows our every step. Even before we utter a word, God already knows what we will say. Yes, the Lord knows all things.
No man can instruct Jesus about anything, including what lies in a man's heart. As the image of the invisible God, who is the exact reflection of His glory and the unalterable representation of His nature, Jesus is aware of everything and knows everything.
