But he [Jesus] would often withdraw to desolate places and pray.
Jesus wasn't merely praying as an example. His praying was Him entering into time and space and making a difference. His praying actually resulted in Him, at times, being strengthened (Luke 22:41-43). He told His disciples that it was a result of His praying that they would be able to continue in their relationship with God -
...but I have prayed for you that your faith may not fail. And when you have turned again, strengthen your brothers.
There is so much detail of the life of Christ that we don't have. But we do have the repeated record that He was a man who prayed. We know what He prayed, how He prayed, when He prayed and that He prayed. But we are less clear on why He prayed.
Some teach that He prayed because He was just a man. Others teach that He prayed because, although He was God, He had relinquished His deity and was not able to use His rights as God. But neither of these positions is Biblical. While Christ became man, He never ceased being God. He as God in the flesh.
The fact that He prayed at all is very striking. The fact that He prayed as a lifestyle is even more striking. At the very least we should be motivated to pray as a lifestyle. This means praying purposefully (setting aside time to pray, even if its only a few minutes), praying silently (while about our daily routines and activities), praying through a list of requests, praying the principles of the Lord's Prayer and making the prayers of the Bible our own.
