And it came to pass in those days, that he went out into a mountain to pray, and continued all night in prayer to God.
All Commentaries on Luke 6:12 Go To Luke 6
Ambrose of Milan
AD 397
So the Lord prays, not to entreat for himself but to intercede for me. Although the Father placed all things in the power of his Son, yet the Son, in order to fulfill the form of a man, thinks that the Father must be entreated for us, because he is our Advocate…. If he is an Advocate, he must intercede on account of my sins…. It says, “He passed the whole night in prayer.” A model is given to you. A form is prescribed which you must imitate…. Unless I am mistaken, it is nowhere found that he prayed with the apostles. Everywhere he entreats alone, for human prayers do not grasp the counsels of God, nor can anyone share with Christ in the inward mysteries. –.
