This is in the Lord's Prayer. What does it mean?
The King owns everything. If you belong to The Kingdom of God then all you have has been given to you by The King to be steward of. In other words you do with it what He tells you to do with it.
The Power. All authority and power (control) belongs to The King so He can enforce what He declares. So The Father can do for us all that He promised through Jesus and He alone must be obeyed.
The Glory for whatever happens belongs solely to The Father. This is because He provides for it to be done so you can do it and you have not done it but only did what The Father has prepared for you and enabled you to do.
These are the basis of all we do for The Father and Jesus.
