Jesus was passionate about His prayer life, it was something He was always doing.

S.D. Gordon in his book, Quiet Talks on Prayer, says

How much prayer meant to Jesus! It was not only his regular habit, but his resort in every emergency, however slight or serious. When perplexed he prayed. When hard pressed by work he prayed. When hungry for fellowship he found it in prayer. He chose his associates and received his messages upon his knees.

If tempted, he prayed.

If criticized, he prayed.

If fatigued in body or wearied in spirit,

He had recourse to his one unfailing habit of prayer. Prayer brought him unmeasured power at the beginning and kept the flow unbroken and undiminished. There was no emergency, no difficulty, no necessity, no temptation that would not yield to prayer.
