“In those days he departed to the mountain to pray, and he spent the night in prayer - to God.”
In Luke 6:12 we see Jesus praying in the night. Sometimes He would spend the entire night in prayer. It is highly unlikely that the Lord did this every night, but it was a common practice of His. This is something that we can do too, not in a legalistic way which would not be profitable, but also not to neglect this practice completely. An easy way to do this would be to pray whenever we awaken in the middle of the night.
We could pray to repair the damage that is often done at night in the cover of darkness.
“the night is advanced, the day is at hand. Let us then throw off the works of darkness [and] put on the armor of light; let us conduct ourselves properly as in the day, not in orgies and drunkenness, not in promiscuity and licentiousness, not in rivalry and jealousy.” Romans 13: 12-13
We could also pray for those in need: those suffering some sickness or who are enduring some incredible pain or those who are lonely, lost and downtrodden.
“the prayer of faith will save the sick person, and the Lord will raise him up.” James 5 :15
Whenever we awaken in the night, we can start praying for anyone who comes to mind or perhaps pick up the rosary meditating on the mysteries of our Lord and His mother. We should not pray with anxiety about all this that goes on in the world but with great calm, trusting that the prayers are doing good in the world. And if we should happen to drift off back to sleep before completing the prayers, this too should not disturb our peace and calm.
We should pray even before going to sleep, spending at least 15 minutes in prayer before drifting off to sleep. Then when some time in the night we awaken, we can begin prayer again. Praying at night, however, should always be in God’s control.
Praying in our beds when we awaken in the middle of the night is an ideal place to pray. It is a place that is solitary, quiet and undistracting for the senses, since it is dark. (cf. Ascent of Mount Carmel, Book 3, ch 39) These night hours or minutes when the world is hushed in slumber are precious alone moments with God in undisturbed communion with Him and is a way to pray always.
