Read: Luke 6:12-16
In these days he went out to the mountain to pray, and all night he continued in prayer to God. (Luke 6:12 ESV)
Jesus had a big decision to make: Out of all the people that had started following him, who would become his apostles? To help him choose he did what we frequently see him do, he prayed. It wasn't a short prayer. It was a token acknowledgement of a scenario that was too large for him. It was an earnest search for guidance.
In the past my wife and I had a student that would ask to use our guest room as a place of prayer at night so as not to disturb his roommate. I nearly always obliged as these requests always came in the midst of a pressing situation in his life. In fact I have always admired his willingness to spend such a long time seeking God's guidance in the meaningful matters of life, as well as his faith in believing that he can hear from the Father in a way that is practical enough to act upon.
That's what Jesus did on the mountain that night. He prayed for an urgent need. He deliberated in the Spirit for quite a long time. He allowed God to guide him in a specific direction and he acted upon it.
What would it take for us to pray like that? I have to admit I rarely spend that kind of time in deliberate prayer. What kind of difference would it make in our decision making? When faced with life's tough choices would it make those choices easier? Perhaps not, but I believe that even in the most difficult of situations it would afford a measure of peace.
