Who is every soul to be subject to?

Are they earthly powers or heavenly powers? Earthly authorities or heavenly authorities? Who is every soul to be subject to?

The answer to whom these powers Paul is referring to is found in 1 Peter 3:22 where the Greek word 'exousia' is translated as 'authorities'.

Jesus Christ Who is gone into heaven, and is on the right hand of God; angels and authorities and powers being made subject unto him.
1 Peter 3:22

The enemies of Christ

In Ephesians 6:12 Paul writes:
For we wrestle not against flesh and blood, but against principalities, against powers, against the rulers of the darkness of this world, against spiritual wickedness in high places.
The Greek word for 'powers' in this verse is also 'exousia'. This suggests that there are heavenly powers opposed to being made subject to Christ.

And David himself saith in the book of Psalms, The LORD said unto my Lord, Sit thou on my right hand, Till I make thine enemies thy footstool.
Luke 20:42-43

The power & authority of the dragon

In Revelation 13:2 And the beast which I saw, was like unto a Leopard, and his feet were as [the feet] of a Bear, and his mouth as the mouth of a Lion: and the dragon gave him his power, and his seat, and great authority.
The Greek word 'exousia' is also used here for authority. Here we read of an earthly power being set up in opposition to Christ's power/authority.

Speaking to hierarchies

When His disciples were arguing among themselves as to who was the greatest, Jesus said, "he that is greatest among you, let him be as the younger; and he that is chief, as he that does serve." Jesus himself was among them as a servant.
Luke 22:24-27

Simple Reduction

If every soul submitted themselves to Christ's authority then the earthly heirachical systems of men from religions, secret societies, military and governments would be no more. Everyone would be servants of God and to each other just as Christ.

We should pray for those who assume authority over men, and those who oppose the authority of Christ.

Then cometh the end, when he shall have delivered up the kingdom to God, even the Father; when he shall have put down all rule and all authority and power.
1 Corinthians 15:24 KJV

Once again the word used for 'authority' in this verse is 'exousia'.

This time of the end in 1 Corinthians 15:25 also lines up with Daniel 12:7 where it is revealed to Daniel that when he (Jesus Christ) has accomplished to scatter (dash into pieces) the power of the holy people, all these things shall be finished.

Who are the holy people?

At the first advent of Christ there were many enemies who sought his life from King Herod who murdered all the infants in Bethlehem in an attempt to destroy Jesus. Then during Christ's ministry it was the Pharisees who sought his life. The Pharisees rejected the teachings of Christ and feared his popularity would make them redundant to the point that they would falsely accuse him, manipulate the people and the Roman governor Pilate to have Jesus executed. The Pharisees were duplicitous in every sense, on the outside acting as though they were a holy people dedicated to God whilst on the inside they were prepared to do any wicked deed to maintain their grip of control, to laud themselves, and live off the blessings and productivity of others. They hijacked the Word of God in particular the sabbath and weaponised it against the people. Jesus saw right through them and exposed them but they would not let the holy spirit convict them, and refused to be healed. Destruction came upon them and their temple in 70 AD and the people were scattered as Jesus had prophesised.

Revelation was then given to the Apostle John warning of more false prophets and of a beast system empowered by the dragon (Satan) that would seek worship from all of mankind but with the hope that all who overcome this system and do not conform rather trusting in God, keeping his commandments and having the testimony of Jesus Christ will be saved. Revelation sets the stage, exposes the actors and unpacks the play book that will lead to the fulfillment of the Gentiles where all the nations conspire, and ending with the final judgement and consummation with all authority and power put down.

It is so important to note that there is no one holy except Amighty God, there are no superior races of man in the eyes of God. He is not a respector of persons, so no matter who you may claim to be related to in the flesh or how much gold, silver or precious stones or money you may have or what position you may hold or how many fancy titles or costumes you have it will not sway you any favour with our creator. We are all made from the same stuff, the same blood and we are all sinful by nature, hence why we all need to put our trust, faith and hope in Jesus Christ.

For all have sinned and fall short of the glory of God.
Romans 3:23.

Thy will be done - God's plan of salvation

Ultimately it is about all souls submitting to doing God's will on earth as it is done in heaven as Jesus said in the Lord's prayer. What is God's will for us? At the foundation it is about keeping God's commandments and having the testimony of Jesus Christ. It is about spreading the Gospel (the good news) that Jesus Christ died for our sins and was ressurected from the dead and all those who believe on him will to be resurected into eternal life.

Blessed are they that do his commandments, that they may have right to the tree of life, and may enter in through the gates into the city.
For without [are] dogs, and sorcerers, and whoremongers, and murderers, and idolaters, and whosoever loveth and maketh a lie.
Revelation 22:14-15

Jesus said to him, “I am the way, the truth, and the life. No one comes to the Father except through Me.
John 14:6
