We could take weeks to look at the meaning of each verse means, but as an introduction we can focus on lines which are especially of interest.

Our Father in heaven,

I think the way the unbelieving world takes this line is to assign or promote God to a place “upstairs” while we get on with doing things how we like downstairs.
But as we saw when we looked at our understanding of Heaven, while God is beyond space and time, as He is the creator of those, He is not remote, mysterious, or distant. He is present with us in a personal way, and His nature has been made clearly known to us in Jesus.
But to say “In heaven” also acknowledges He is almighty, perfect in wisdom, goodness and righteousness.

Our Father

This address shows we can approach Him in prayer with boldness and confidence, knowing that He wants only what is good and best for us.

Hallowed be Your name.

The “name” indicates the person. God’s name is perfectly holy, but we pray His name may be holy to us, We pray that we may acknowledge and worship the person of God as He truly is, and respond with thankful and humble trust and obedience.
Many years ago some churches tried to promote Christianity by proclaiming that Jesus is simply “your best mate”, which implies he happily accepts you as you are. He is our best mate only because he is not happy for us to remain as we are, for He went to the cross to save us from our slavery to sin and death.
When people try to reinterpret God’s word to our own advantage, and dream up doctrines and empty philosophy of our own making, we are rejecting the person of God amongst us, and making our own gods.

10 Your kingdom come.

I can think of two aspects to this prayer:

1) We think of the end times with Jesus’ return in judgement, when God’s perfect justice will be applied in all its fullness, with a new heaven and a new earth.

2) But I also think of Jesus statement in Luke 17:20-21, “The kingdom of God does not come with observation; nor will they say, ‘See here!’ or ‘See there!’ For indeed, the kingdom of God is within you.” The kingdom comes when we receive the Holy Spirit and believe in Jesus, and respond in obedience to do his will. That is where I ask the kingdom to begin, in my life.

Your will be done On earth as it is in heaven.

We pray for God’s intervention and justice in this world, that people may follow his will instead of following Satan and their own sinful nature.

But again, may that begin with me. May my thoughts and actions be truly according to His will, just as Jesus prayed in Matthew 26:39 “not as I will, but as You will.”
And may I receive with joy the Christian friends and guides that God sends into my life to correct and keep me focussed on obedience to God.

11 Give us this day our daily bread.

As Psalm 145 describes, God does supply our daily needs, “You open Your hand And satisfy the desire of every living thing.” This line asks that our eyes be opened to recognize and acknowledge God as the one who provides for our daily needs, and to respond with thankfulness. And we also pray for contentment with God’s provision, that we not turn to greed for what we do not need.

12 And forgive us our debts, As we forgive our debtors.

This line is usually spoken with “trespasses” or “sins”.

We recognise that we do not deserve to be forgiven, but with these words we express our desire for forgiveness through Jesus and his sacrifice on the cross, to receive the forgiveness He has won for us.

And we pray for a heart to forgive others in the same way as we have been forgiven, that we may be transformed by His Spirit to be like Him in forgiveness. That doesn't mean happily leaving others in their sin, it may even be that the best we can do for another is to take practical measures to make them aware of their sin. It means that we are freed from all bitterness and resentment, to do God's will as we desire the best for the one who has sinned against us.

Psalm 103:10-12, “For as the heavens are high above the earth, So great is His mercy toward those who fear Him; As far as the east is from the west, So far has He removed our transgressions from us.”

13 And do not lead us into temptation, But deliver us from the evil one.

We pray that God would guard us and keep us safe, so that Satan and this world and our own fallen nature would not lead us into the idolatory of worship of this world’s gods.

James 4:7, “Therefore submit to God. Resist the devil and he will flee from you.”

For Yours is the kingdom and the power and the glory forever. Amen.

As we acknowledge who God is, we can be fully confident in His power to answer our prayers.

So, we are to give him the glory for our faithful response, and not take pride in ourselves.

And we look to an eternity with Him.

On the dangers of trying to promote God upstairs, I searched out the origin of the saying “God's in his heaven — and All's right with the world!”
It comes from “Pippa's Song” in an 1841 verse “Pippa Passes” by Robert Browning.
Pippa is a young, innocent girl, and on her only holiday of the entire year she wanders through the hills and streets singing happily to herself. She is quite unaware of the evil around her on her walk, which includes a man who has just murdered his lover’s husband, a would be assassin, and various other evil characters.

So both statements are wrong. All is not right with the world, it is in a fallen state of sin. But fortunately God is not secluded upstairs, He is with us and guiding us for His good purpose, giving His blessings on a world that would prefer to choose disaster.
