The model prayer of Matthew 6 and Luke 11, Jesus didn't pray. He was teaching His disciples how to pray. Certain few times the New Testament records that He spoke to His Father, He didn't ask for anything. He prays for one thing in John 12:28, "Father, glorify thy name."
On the cross in Luke 23:34, Jesus prays, "Father, forgive them." He prayed three times in the Garden of Gethsemane in Matthew 26, two of which He requested essentially the same thing, and the third time it says he prayed the same thing as the first two. In verse 39, He prayed, "Not as I wilt, but as thou wilt," regarding His suffering and death, and then in verse 42, "Thy will be done," which was about the same thing.
14 I have given them thy word; and the world hath hated them, because they are not of the world, even as I am not of the world. 15 I pray not that thou shouldest take them out of the world, but that thou shouldest keep them from the evil. 16 They are not of the world, even as I am not of the world.
17 Sanctify them through thy truth: thy word is truth. 18 As thou hast sent me into the world, even so have I also sent them into the world. 19 And for their sakes I sanctify myself, that they also might be sanctified through the truth. 20 Neither pray I for these alone, but for them also which shall believe on me through their word.
15 Love not the world, neither the things that are in the world. If any man love the world, the love of the Father is not in him. 16 For all that is in the world, the lust of the flesh, and the lust of the eyes, and the pride of life, is not of the Father, but is of the world. 17 And the world passeth away, and the lust thereof: but he that doeth the will of God abideth for ever.
They went out from us, but they were not of us; for if they had been of us, they would no doubt have continued with us: but they went out, that they might be made manifest that they were not all of us.
For if after they have escaped the pollutions of the world through the knowledge of the Lord and Saviour Jesus Christ, they are again entangled therein, and overcome, the latter end is worse with them than the beginning.
