And immediately the Spirit drove him out into the desert.

“(Hom in Matt. xiii) Because all that Christ did and suffered was for our teaching, He began after His baptism to dwell in the wilderness, and fought against the devil, that every baptized person might patiently sustain greater temptations after His baptism, nor be troubled, as if this which happened to Him was contrary to His expectation, but might bear up against all things, and come off conqueror. For although God allows that we should be tempted for many other reasons, yet for this cause also He allows it, that we may know, that man when tempted is placed in a station of greater honour. For the Devil approaches not save where he has beheld one set in a place of greater honour; and therefore it is said, And immediately the Spirit drove him into the wilderness. And the reason why He does not simply say, that He went into the wilderness, but was driven, is, that thou mayest understand that it was done according to the word of Divine Providence. By which also He shews, that no man should thrust himself into temptation, but that those who from some other state are as it were driven into temptation, remain conquerors.”

“(in Marc. i. 5) And that no one might doubt, by what spirit he said that Christ was driven into the wilderness, Luke has on purpose premised, that Jesus being full of the Spirit returned from Jordan, (Luke 4:12) and then has added, and was led by the Spirit into the wilderness; lest the evil spirit should be thought to have any power over Him, who, being full of the Holy Spirit, departed whither He was willing to go, and did what He was willing to do.”

“And immediately,.... As soon as he was baptized, and this testimony had been given of his divine sonship, the very selfsame day, the Spirit driveth him into the wilderness: into a more remote and desolate part of it; for it was in the wilderness John was baptizing and preaching, when Christ came to him, and had the ordinance of baptism administered by him; and it was the same Spirit that descended on him at his baptism, which remained with him; by whose impulse he was moved, though not against his will, to go into, this desert and forlorn place. For this was not the evil spirit Satan, by whom he was tempted; for Matthew expressly says, that he was "led up of the Spirit--to be tempted by the devil", Mat 4:1, where the devil that tempted him, is manifestly distinguished from the Spirit by whom he was led, and the same Spirit is meant here, as there. Moreover, in one of Beza's copies, and in his most ancient one, and in one of Stephens's, it is read, "the Holy Spirit driveth him"; See Gill on Mat 4:1.”
