The Universe Trial
Near the end of the mountain sojourn Jesus asked his Father if he might be permitted to hold conference with his Satania enemies as the Son of Man, as Joshua ben Joseph. This request was granted. During the last week on Mount Hermon the great temptation, the universe trial, occurred. Satan (representing Lucifer ) and the rebellious Planetary Prince, Caligastia, were present with Jesus and were made fully visible to him. And this “temptation,” this final trial of human loyalty in the face of the misrepresentations of rebel personalities, had not to do with food, temple pinnacles, or presumptuous acts. It had not to do with the kingdoms of this world but with the sovereignty of a mighty and glorious universe. The symbolism of your records was intended for the backward ages of the world's childlike thought. And subsequent generations should understand what a great struggle the Son of Man passed through that eventful day on Mount Hermon. ~ The Urantia Book, 134:8.6
Jesus Met and Defeated Evil
Jesus had endured the great temptation of his mortal bestowal before his baptism when he had been wet with the dews of Mount Hermon for six weeks. There on Mount Hermon, as an unaided mortal of the realm, he had met and defeated the Urantia pretender, Caligastia, the prince of this world. That eventful day, on the universe records, Jesus of Nazareth had become the Planetary Prince of Urantia. And this Prince of Urantia, so soon to be proclaimed supreme Sovereign of Nebadon, now went into forty days of retirement to formulate the plans and determine upon the technique of proclaiming the new kingdom of God in the hearts of men. ~ The Urantia Book, 136:3.1
The Forty Days of Isolation
Jesus did not fast during this forty days' isolation. The longest period he went without food was his first two days in the hills when he was so engrossed with his thinking that he forgot all about eating. But on the third day he went in search of food. Neither was he tempted during this time by any evil spirits or rebel personalities of station on this world or from any other world. ~ The Urantia Book, 136:4.3
Jesus in the Wilderness
These forty days were the occasion of the final conference between the human and the divine minds, or rather the first real functioning of these two minds as now made one. The results of this momentous season of meditation demonstrated conclusively that the divine mind has triumphantly and spiritually dominated the human intellect. The mind of man has become the mind of God from this time on, and though the selfhood of the mind of man is ever present, always does this spiritualized human mind say, “Not my will but yours be done.” ~ The Urantia Book, 136:4.4
The Final Trial
And this "temptation, " this final trial of human loyalty in the face of the misrepresentations of rebel personalities, had not to do with food, temple pinnacles, or presumptuous acts. It had not to do with the kingdoms of this world but with the sovereignty of a mighty and glorious universe. ... And subsequent generations should understand what a great struggle the Son of Man passed through that eventful day on Mount Hermon.
