Thus, when we end a prayer with this word we are stating that we are in agreement with what has been said.

The final doxology 

• This ending was not originally included in the Lord's Prayer, not is it officially a part of the  prayer.
• Doxology is a word that means: A spoken/sung expression of praise of God

"For the kingdom, the power and the glory are yours, now and forever,"

• This ending was not originally included in the Lord's Prayer, not is it officially a part of the  prayer.
• This final doxology brings us back to the first three petitions of the Lord's Prayer: 
  • the glory of his name
  • the coming of his Kingdom
  • and the power of his saving will
• But these prayers are now proclaimed as adoration and thanksgiving, as opposed to petitions of prayer.
