For your consideration.

The wording "my gospel" is found only three times in the bible and all three were spoken by Paul post-crucifixion. Paul was handpicked to be the apostle to the Gentiles. Galatians 1:12 tells us that the gospel that Paul preached was revealed to him by Jesus Christ. That makes "my gospel" from Paul set apart, or sanctified,  from the other four gospels in that it is the only post-crucifixion gospel by which the Gentiles are saved. It does not include the Lord's Prayer which was given to the Jews only.  

Romans 2:16 In the day when God shall judge the secrets of men by Jesus Christ according to my gospel.

Romans 16:25 Now to him that is of power to stablish you according to my gospel, and the preaching of Jesus Christ, according to the revelation of the mystery, which was kept secret since the world began,

Timothy 2:8 Remember that Jesus Christ of the seed of David was raised from the dead according to my gospel:

Galatians 1:12 For I (Paul) neither received it of man, neither was I taught it, but by the revelation of Jesus Christ.

Come Lord Jesus.
