Ephesians 5:21

Be subject to one another out of reverence for Christ (the Messiah, the Anointed One). Ephesians 5:21

Our Father tells us that Jesus ever lives to serve us so that we may be saved to the uttermost and He also tells us that we are now one with Him. Jesus is now our Head, so this means that we will be used by Him to serve as He serves. We are absolutely part of the solution. We are members of Jesus’ body, so we have to be used by Him. If Jesus couldn’t use us then wouldn’t He be a cripple? So there are no maybe’s about it, you and I will be used to serve. We have been filled with the same Holy Spirit that Jesus has been filled with to be used. Jesus also has given us the exact same glory that He has so that we can be used. All of this has happened so that we may be used by our Father to do the works that Jesus did and even greater ones. 

The Truth is that we can’t help but to be subject to one another because we are all one with each other.

I have given to them the glory and honor which You have given Me, that they may be one [even] as We are one: I in them and You in Me, in order that they may become one and perfectly united, that the world may know and [definitely] recognize that You sent Me and that You have loved them [even] as You have loved Me. Father, I desire that they also whom You have entrusted to Me [as Your gift to Me] may be with Me where I am, so that they may see My glory, which You have given Me [Your love gift to Me]; for You loved Me before the foundation of the world. John 17:22-24

Because of Jesus we are perfectly united. There are no divisions in Christ and we are all in Christ. We are subject to one another because Jesus will have it no other way. If there is anything in us that would ever hinder us from being subject to one another our Father is obligated to prune it out of us. 

But the person who is united to the Lord becomes one spirit with Him. 1 Corinthians 6:17

For in Christ Jesus you are all sons of God through faith. For as many [of you] as were baptized into Christ [into a spiritual union and communion with Christ, the Anointed One, the Messiah] have put on (clothed yourselves with) Christ. There is [now no distinction] neither Jew nor Greek, there is neither slave nor free, there is not male and female; for you are all one in Christ Jesus. Galatians 3:26-28

But the fruit of the [Holy] Spirit [the work which His presence within accomplishes] is love, joy (gladness), peace, patience (an even temper, forbearance), kindness, goodness (benevolence), faithfulness, Gentleness (meekness, humility), self-control (self-restraint, continence). Against such things there is no law [that can bring a charge]. And those who belong to Christ Jesus (the Messiah) have crucified the flesh (the godless human nature) with its passions and appetites and desires. If we live by the [Holy] Spirit, let us also walk by the Spirit. [If by the Holy Spirit we have our life in God, let us go forward walking in line, our conduct controlled by the Spirit.] Galatians 5:22-25
