The prayer begins by stating that our Father in the Heavens has a name and it is 'hallowed'. Hallowed - primarily meaning: set-apart, or consecrated, sacred, sanctified and revered. Most Christian denominations pray this prayer yet they don't even use His set-apart name.
The prayer tends to be taught and recited and becomes a repetitive custom rather than a heartfelt prayer. Most people then recite it without even thinking or questioning its content.
Let's ask a few questions:
1) What is our Heavenly Father's set-apart name?
2) Is His name really important?
