Luke 5:16

(26.) And His works He indeed performed among the people, but He prayed for the most part in the wilderness, sanctioning the liberty of resting a while from labour to hold converse with God with a pure heart. For He needed no change or retirement, since there was nothing which could be relaxed in Him, nor any place in which He might confine Himself, for He was God, but it was that we might clearly know that there is a time for action, a time for each higher occupation.

(Mor. xxviii. c. 13.) Our Redeemer performs His miracles by day, and passes the night in prayer, as it follows, And he withdrew himself into the wilderness, and prayed, hinting, as it were, to perfect preachers, that as neither they should entirely desert the active life from love of contemplation, so neither should they despise the joys of contemplation from an excess of activity, but in silent thought imbibe that which they might afterwards give back in words to their neighbours.

Now that He retired to pray, you would not ascribe to that nature which says, I will, be thou clean, but to that which putting forth the hand touched the leprous man, not that according to Nestorius there is a double person of the Son, but of the same person, as there are two natures, so are there two operations.
