Note: Insincere is used once and with regard to Lucifer:
(53:2.5) It is very difficult to point out the exact cause or causes which finally culminated in the Lucifer rebellion. We are certain of only one thing, and that is: Whatever these first beginnings were, they had their origin in Lucifer’s mind. There must have been a pride of self that nourished itself to the point of self-deception, so that Lucifer for a time really persuaded himself that his contemplation of rebellion was actually for the good of the system, if not of the universe. By the time his plans had developed to the point of disillusionment, no doubt he had gone too far for his original and mischief-making pride to permit him to stop. At some point in this experience he became insincere, and evil evolved into deliberate and willful sin. That this happened is proved by the subsequent conduct of this brilliant executive. He was long offered opportunity for repentance, but only some of his subordinates ever accepted the proffered mercy. The Faithful of Days of Edentia, on the request of the Constellation Fathers, in person presented the plan of Michael for the saving of these flagrant rebels, but always was the mercy of the Creator Son rejected and rejected with increasing contempt and disdain.
Insincerity is used six times:
(9:5.7) Too often, all too often, you mar your minds by insincerity and sear them with unrighteousness; you subject them to animal fear and distort them by useless anxiety. Therefore, though the source of mind is divine, mind as you know it on your world of ascension can hardly become the object of great admiration, much less of adoration or worship. The contemplation of the immature and inactive human intellect should lead only to reactions of humility.
(48:5.8) One of the purposes of the morontia career is to effect the permanent eradication from the mortal survivors of such animal vestigial traits as procrastination, equivocation, insincerity, problem avoidance, unfairness, and ease seeking. The mansonia life early teaches the young morontia pupils that postponement is in no sense avoidance. After the life in the flesh, time is no longer available as a technique of dodging situations or of circumventing disagreeable obligations.
(82:1.10) No human emotion or impulse, when unbridled and overindulged, can produce so much harm and sorrow as this powerful sex urge. Intelligent submission of this impulse to the regulations of society is the supreme test of the actuality of any civilization. Self-control, more and more self-control, is the ever-increasing demand of advancing mankind. Secrecy, insincerity, and hypocrisy may obscure sex problems, but they do not provide solutions, nor do they advance ethics.
(139:1.10) Andrew was a man of clear insight, logical thought, and firm decision, whose great strength of character consisted in his superb stability. His temperamental handicap was his lack of enthusiasm; he many times failed to encourage his associates by judicious commendation. And this reticence to praise the worthy accomplishments of his friends grew out of his abhorrence of flattery and insincerity. Andrew was one of those all-round, even-tempered, self-made, and successful men of modest affairs.
(173:2.8) And it was this genius of the Master for dealing with his adversaries that made them so afraid of him. They attempted no more questions that day; they retired to take further counsel among themselves. But the people were not slow to discern the dishonesty and insincerity in these questions asked by the Jewish rulers. Even the common folk could not fail to distinguish between the moral majesty of the Master and the designing hypocrisy of his enemies. But the cleansing of the temple had brought the Sadducees over to the side of the Pharisees in perfecting the plan to destroy Jesus. And the Sadducees now represented a majority of the Sanhedrin.
(186:2.8) The Master never displayed the least interest in Pilate’s well-meant but halfhearted efforts to effect his release. He really pitied Pilate and sincerely endeavored to enlighten his darkened mind. He was wholly passive to all the Roman governor’s appeals to the Jews to withdraw their criminal charges against him. Throughout the whole sorrowful ordeal he bore himself with simple dignity and unostentatious majesty. He would not so much as cast reflections of insincerity upon his would-be murderers when they asked if he were “king of the Jews.” With but little qualifying explanation he accepted the designation, knowing that, while they had chosen to reject him, he would be the last to afford them real national leadership, even in a spiritual sense.
