The Lord's Prayer Possessive is a phrase used in the Christian prayer known as the Lord's Prayer. It consists of two words, OUR and THY, which are both three letters long. OUR is a possessive pronoun meaning belonging to or associated with the speaker and THY is a possessive pronoun meaning belonging to or associated with the person being addressed. Together, they form the phrase 'Our Father, who art in heaven, hallowed be THY name.' This phrase is used to address God in the Lord's Prayer.
