There is perhaps no more striking characteristic of Jesus' mental attitude toward truth than his clarity of vision, the keenness of his insight into the real meanings of things. He did not believe in "cleansing the outside of the cup or of the platter and leaving the inside untouched." He did not think that a courteous manner and fair promises revealed the character of a man. "As a man thinketh in his heart, so is he." He did not believe in long prayers that recite the virtues of the petitioners. God looks into the heart as Jesus did and sees the man as he is.
Moreover, in his interpretation of the law he was not content with the mere word. He must understand the purpose and significance of the law. Life and life's activities were with him not matters of form; they were matters of purpose and intent. When criticised for violation of the law regarding the Sabbath Day, he recognized to the full the sanctity of the day, but claimed that the purpose and not the form of the deed determined its sanctity. "The Sabbath was made for man and not man for the Sabbath." If the purpose of one's acts is the uplift of humanity or the bringing of comfort to a suffering soul, the deed is good, the Sabbath is not broken. These traits of Jesus show clarity of mental vision and mental integrity, the ultimate essence of truth. He does not necessarily condemn the moral integrity of those who keep the letter of the law in good faith, not seeing its spirit; but he does say that they do not know the truth.
Aside from this, however, no other sin of humanity seems so to arouse his righteous indignation as does wilful misrepresentation, conscious hypocrisy. "When ye pray, ye shall not be as hypocrites: for they love to stand and pray in the synagogues and in the corners of the streets, that they may be seen of men. Verily I say unto you, they have received their reward" (Matt. 6:5).
"Woe unto you, scribes and Pharisees, hypocrites! for ye tithe mint and anise and cummin, and have left undone the weightier matters of the law, justice, and mercy, and faith: but these ye ought to have done, and not to have left the other undone.... Woe unto you, scribes and Pharisees, hypocrites! for ye are like unto whited sepulchres, which outwardly appear beautiful, but inwardly are full of dead men's bones, and of all uncleanness. Even so ye also outwardly appear righteous unto men, but inwardly ye are full of hypocrisy and iniquity" (Matt. 23:23, 27, 28).
