Why do Christians say Jesus is Lord?

Matthew 28 vs. 18:

All authority has been given to me in heaven and on earth”

1. By the authority in the name of Jesus, I decree an end to every problem afflicting my life in Jesus name.
2. I claim authority over every authority working contrary to my breakthroughs in Jesus name.
3. Evil authorities on earth attacking my life, I paralyze you in Jesus name.
4. Satanic authorities in the heave lies assigned against my life, die in Jesus name.
5. Name of Jesus; make a way for me where there is no way.
