The Bible has an order, You see that the Apostles acts come after the Gospels. Which makes sense of course, and then, will the Apostle Paul will come, but in the Acts we learn specifically, that we should say the Our Father prayer, and we think that this prayer is like all the others. It’s not like all the others, the others are more researched in regards to the consistency of the church.
This is the source.
The source persists.
So, Christ says, when you have one prayer, one not two, but one, say that one at least. And He persists, and that is of great importance, that the Our Father prayer should not be considered to be a prayer, just like any other. Because, sometimes children learn other prayers at school, assuming that it’s the same or it will be easier.
Remember that, the Our Father prayer is difficult for everyone. Because, if we were to be taught something easy by Christ, then that would’nt have been a Teaching. The Our Father prayer, is a very condensed subject, and if, while we were saying it, we could really hear what we were saying, then we would not say it with such ease.
