Were Jesus' prayers ritualistic? He would sometimes pray all night and we have no evidence from scripture that God had given Israel prayer rituals to perform. In fact Jesus told us not to use repetition in prayer. Which rells me we are to send up prayers that are meaningful to us at the moment we pray.
There is a difference between repetition and using a prayer model. In a moment I will post from Ellen White's Thoughts from the Mount of Blessing where she discusses the Lord's prayer. I post from her because you are more likely to hear it from her.
It points out that He did intend it to be a model for the disciples. A prayer model doesn't just mean repeating the prayer over and over. It means that each element of Jesus' prayer tells us something about how to pray, in our own words.
That Jesus intended the disciples to use it this way is also clear from Scripture. It is in the very context of speaking of not using vain repetition that Jesus introduces the Lord's prayer as a prayer model. Since he introduces it as a proper alternative to vain repetition, we know it is not, in fact, vain repetition.
Matthew 6:7 And when you pray, do not use vain repetitions as the heathen
do. For they think that they will be heard for their many words. 8 “Therefore do not be like them. For your Father knows the things you have need of before you ask Him.
9 In this manner, therefore, pray:
Here is Ellen White discussing how the prayer is a model:
So ready, so eager, is the Saviour's heart to welcome us as members of the family of God, that in the very first words we are to use in approaching God He places the assurance of our divine relationship, 'Our Father.'

Thoughts from the Mount of Blessing, chapter 5, Ellen White
"After this manner therefore pray ye." Matthew 6:9.
The Lord's Prayer was twice given by our Saviour, first to the multitude in the Sermon on the Mount, and again, some months later, to the disciples alone. The disciples had been for a short time absent from their Lord, when on their return they found Him absorbed in communion with God. Seeming unconscious of their presence, He continued praying aloud. The Saviour's face was irradiated with a celestial brightness. He seemed to be in the very presence of the Unseen, and there was a living power in His words as of one who spoke with God. {MB 102.1}
The hearts of the listening disciples were deeply moved. They had marked how often He spent long hours in solitude in communion with His Father. His days were passed in ministry to the crowds that pressed upon Him, and in unveiling the treacherous sophistry of the rabbis, and this incessant labor often left Him so utterly wearied that His mother and brothers, and even His disciples, had feared that His life would be sacrificed. But as He returned from the hours of prayer that closed the toilsome day, they marked the look of peace upon His face, the sense of refreshment that seemed to pervade His presence. It was from hours spent with God that He came forth, morning by morning, to bring the light of heaven to men. The disciples had come to [103] connect His hours of prayer with the power of His words and works. Now, as they listened to His supplication, their hearts were awed and humbled. As He ceased praying, it was with a conviction of their own deep need that they exclaimed, "Lord, teach us to pray." Luke 11:1. {MB 102.2}
Jesus gives them no new form of prayer. That which He has before taught them He repeats, as if He would say, You need to understand what I have already given. It has a depth of meaning you have not yet fathomed. {MB 103.1}
The Saviour does not, however, restrict us to the use of these exact words. As one with humanity, He presents His own ideal of prayer, words so simple that they may be adopted by the little child, yet so comprehensive that their significance can never be fully grasped by the greatest minds. We are taught to come to God with our tribute of thanksgiving, to make known our wants, to confess our sins, and to claim His mercy in accordance with His promise. {MB 103.2}
