“Then was Jesus led up of the Spirit into the wilderness, to be tempted of the devil.”
Then. When? After the descent of the Spirit, after the voice that was borne from above, and said, “This is My Beloved Son, in whom I am well pleased.” And what was marvellous, it was of the Holy Spirit; for this, he here saith, led Him up. For since with a view to our instruction He both did and underwent all things; He endures also to be led up thither, and to wrestle against the devil: in order that each of those who are baptized, if after his baptism he have to endure greater temptations may not be troubled as if the result were unexpected, but may continue to endure all nobly, as though it were happening in the natural course of things.
Yea, for therefore thou didst take up arms, not to be idle, but to fight. For this cause neither doth God hinder the temptations as they come on, first to teach thee that thou art become much stronger; next, that thou mayest continue modest neither be exalted even by the greatness of thy gifts, the temptations having power to repress thee; moreover, in order that that wicked demon, who is for a while doubtful about thy desertion of him, by the touchstone of temptations may be well assured that thou hast utterly forsaken and fallen from him; fourthly, that thou mayest in this way be made stronger, and better tempered than any steel; fifthly, that thou mayest obtain a clear demonstration of the treasures entrusted to thee.
For the devil would not have assailed thee, unless he had seen thee brought to greater honor. Hence, for example, from the beginning, he attacked Adam, because he saw him in the enjoyment of great dignity. For this reason he arrayed himself against Job, because he saw him crowned and proclaimed by the God of all.
How then saith He, “Pray that ye enter not into temptation.” For this cause he doth not show thee Jesus simply going up, but “led up” according to the principle of the Economy; signifying obscurely by this, that we ought not of ourselves to leap upon it, but being dragged thereto, to stand manfully.
And see whither the Spirit led Him up, when He had taken Him; not into a city and forum, but into a wilderness. That is, He being minded to attract the devil, gives him a handle not only by His hunger, but also by the place. For then most especially doth the devil assail, when he sees men left alone, and by themselves.
