Why just principles? Why not all of it?
There is nothing to prevent a Christian from repeating each phrase of the Lord's Prayer (as commonly know) and then applying that principle immediately thereafter, if it assists in his praying. To review the principles let's take another look at Matthew's Gospel and see how powerful this brief prayer is. We should also remember that it was given in order to teach us how to pray:
1. GOD IN HEAVEN IS THE FATHER OF THE CHILD OF GOD
Our Father which art in Heaven
2. THE FIRST PRIORITY OF PRAYER IS WORSHIP
Hallowed be thy Name
3. WE ARE FIRSTLY TO SEEK HIS KINGDOM AND HIS RIGHTEOUSNESS
Thy Kingdom come
4. GOD'S WILL IS SUPREME
Thy will be done in earth, as it is in Heaven
5. WE MUST PETITION FOR OUR DAILY NEEDS
Give us this day our daily bread
6. WE NEED TO HAVE OUR SINS FORGIVEN DAILY WHILE FORGIVING OTHERS
And forgive us our debts, as we forgive our debtors [we cannot expect forgiveness while we hold grudges]
7. WE NEED TO PRAY TO BE KEPT FROM TEMPTATIONS
And lead us not into temptation
8. WE NEED TO BE DELIVERED FROM EVIL AND THE EVIL ONE
But deliver us from evil
9. WE ARE TO ACKNOWLEDGE THAT GOD'S KINGDOM IS SUPREME AND ETERNAL
For thine is the Kingdom
10. WE ARE TO REMEMBER THAT ALL POWER AND GLORY BELONGS TO GOD FOREVER
And the power and the glory for ever
11. WE ARE TO SINCERELY GIVE ASSENT TO ALL OF THIS
Amen
