Reflection on the Lord's Prayer.
Our Father in heaven. I can't be certain, but I think this is the first time Jesus implies that we are sons and daughters of the Most High.
He doesn't say, "My Father." He says "our Father." He is letting His followers know that we are kin to the Heavenly Kingdom & heirs with Christ.
While praying, Jesus is focusing on God's will being done, not His own. This would happen again in the Garden of Gethsemane before Jesus was arrested and later crucified. He asked God to take this cup (burden) from Him, yet he prayed, "Not my will but Yours be done."
Seek the will of the Father when praying.
"Forgive us as we forgive others." Do we expect God's forgiveness & grace when we withhold it from others?
Give freely, for it has been given freely (and often) to you.
