Now when he was in Jerusalem at the Passover Feast, many believed in his name when they saw the signs that he was doing. But Jesus on his part did not entrust himself to them, because he knew all people and needed no one to bear witness about man, for he himself knew what was in man. ~ John 2:23-25 (ESV)
Jesus did not need the assistance of a psychologist, sociologist, anthropologist, poet laureate or bartender to understand the inner workings of the human mind. He knew people, inside and out. Nor did he need to gain the approval or affirmation of the masses to carry out his task since he did not suffer from low self esteem or insecurity. Instead, from his position of strength, he came to alleviate the deepest need of humanity - estrangement from God the Father.
