Your kingdom come. Your will be done. On earth as it is in heaven. (Matthew 6:10)
All authority has been given to Me in heaven and on earth. (Matthew 28:18)
I am with you always, even to the end of the age. (Matthew 28:20)
His Will is Done in Heaven and His Will will be Done on Earth
Matthew 6:10 tells us that we are to pray for God’s will to be done on earth as it is in heaven. This shows us that in heaven God’s will is done and on earth His will is going to be done in time, His time (a point in time) – using us as His soldiers on earth.
This is important to understand as we discuss Christology: Christ in heaven is outside of time. Christ was before time (2 Timothy 1:8-9) and our call was given to us in Christ before time began. The Greek words aion and aionis are words for time, and specifically used for eternal time. The same Greek word for eternal time is used in Titus 1:1-3 which tells us the hope of salvation in Christ was there before time began (thus the phrase “hope is eternal”). In Hebrews 13:8 where the passage reads, “Jesus is the same yesterday, today, and forever (same word for eternal time):” the proper exegesis is Jesus was always the Christ – He is eternally the Christ. The Son of God was in the beginning and He was the Creator of all things according to John 1:1-3 and 10. In Colossians 1:15-20 Christ is the Creator, the Preeminent One, and before all things – thus eternal. Isaiah 57:15 when speaking of God speaks of Him inhabiting eternity. Acts 15:18 tells us God’s works have been known by Him for all eternity See also: Revelation 1:8, 11, 17; Revelation 2:8; Rev 21:6; Revelation 22:13; Isaiah 41:4; Isaiah 48:12-13; and 1 Corinthians 2:6-9. In contrast, Jesus while incarnate, and we as believers on earth are subject to the limitations of time.
What we as the Church have been given is a promise: God’s will is going to get done on earth and through the Great Commissioning that will is going to be completed (Matthew 6:10). Figuratively the work of Jesus is on earth is done (that is why we say “the finished work of the cross”). Christ’s work in heaven is past, present, and future because Christ is outside of time.
Our work is on earth because we are subject to time. We fulfill the Great Commission on earth, but because we are empowered from on high it was important to the New Testament writers to give us the understanding that all authority is in Christ’s possession, and He delegates some of that authority to us on earth to fulfill His will.
