I used to wonder why the Lord’s Prayer said “in earth” instead of “on earth” so I asked God and studied to find out why. After studying I felt deeply impressed that it has to do with man being made out of “the dust of the ground” because I had also found what it means to hallow the name of the Lord. We hallow God’s name when we keep His commandments and we profane His name when we don’t. So the Lord’s Prayer is us committing ourselves to hallow God’s name in our earthly bodies (God’s temple) by keeping His commandments like the angels do in heaven, “as it is in heaven” (Psalms 103:20). Also we acknowledge God by our actions, by our obedience or we deny Him by our disobedience (Titus 1:16).

Hollowing God’s name:

Leviticus 22:31-33
“Therefore shall ye keep My commandments, and do them: I am the LORD. Neither shall ye profane My holy name; but I will be hallowed among the children of Israel: I am the LORD which hallow you, That brought you out of the land of Egypt, to be your God: I am the LORD.”

Matthew 6:9
“After this manner therefore pray ye: Our Father which art in heaven, Hallowed be Thy name.”

“As In Heaven, so IN earth”

Luke 11:2
“And He said unto them, When ye pray, say, Our Father which art in heaven, Hallowed be Thy name. Thy kingdom come. Thy will be done, as in heaven, so in earth.”

Genesis 2:7
“And the LORD God formed man of the dust of the ground, and breathed into his nostrils the breath of life; and man became a living soul.”

“As In Heaven”

Psalms 103:20
“Bless the LORD, ye His angels, that excel in strength, that do His commandments, hearkening unto the voice of His word.”

Denying God:

Titus 1:16
“They profess that they know God; but in works they deny Him, being abominable, and disobedient, and unto every good work reprobate.”

Acknowledging God:

Proverbs 3:1-7
“My son, forget not My law; but let thine heart keep My commandments: For length of days, and long life, and peace, shall they add to thee. Let not mercy and truth forsake thee: bind them about thy neck; write them upon the table of thine heart: So shalt thou find favour and good understanding in the sight of God and man. Trust in the LORD with all thine heart; and lean not unto thine own understanding. IN ALL THY WAYS ACKNOWLEDGE HIM and He shall direct thy paths. Be not wise in thine own eyes: fear the LORD, and depart from evil.”

When we depart from God by doing our own will, the will of the flesh, instead of choosing to do His perfect will, we are telling and showing God that we trust in our own judgement and not His. The apostle Paul in 2 Corinthians 1:9 warns us not to trust in our own judgement because when we did that we created the death penalty that comes from sinning.

2Corinthians 1:9
“But we had the sentence of death in ourselves, that we should not trust in ourselves, but in God which raiseth the dead”.
