Colossians 1:18-20

18 He also is the Head of [His] body, the church; seeing He is the Beginning, the Firstborn from among the dead, so that He alone in everything and in every respect might occupy the chief place [stand first and be preeminent]. For it has pleased [the Father] that all the divine fullness (the sum total of the divine perfection, powers, and attributes) should dwell in Him permanently. And God purposed that through (by the service, the intervention of) Him [the Son] all things should be completely reconciled back to Himself, whether on earth or in heaven, as through Him, [the Father] made peace by means of the blood of His cross. Colossians 1:18-20

The Head directs all of the Body. Nothing can happen with the body unless the head empowers and directs it to happen. Whether it is conscious or unconscious makes no difference, nothing happens without the head empowering it.

For in Him we live and move and have our being; as even some of your [own] poets have said, For we are also His offspring. Since then we are God's offspring, we ought not to suppose that Deity (the Godhead) is like gold or silver or stone, [of the nature of] a representation by human art and imagination, or anything constructed or invented. Acts 17:28-29

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

Also we are shown here that all things are now reconciled in Heaven and on Earth back to our Father. Reconciled means to that all differences have been settled, things coexist in harmony, things are compatible, and to make one account consistent with the other. All things are now in complete harmony because of what Jesus did, He was that successful on the Cross. Because of Christ we cannot be defeated, everything has been completely settled for us. 

But thanks be to God, Who in Christ always leads us in triumph [as trophies of Christ's victory] and through us spreads and makes evident the fragrance of the knowledge of God everywhere, 2 Corinthians 2:14

I have strength for all things in Christ Who empowers me [I am ready for anything and equal to anything through Him Who infuses inner strength into me; I am self-sufficient in Christ's sufficiency]. Philippians 4:13

And may the God of peace Himself sanctify you through and through [separate you from profane things, make you pure and wholly consecrated to God]; and may your spirit and soul and body be preserved sound and complete [and found] blameless at the coming of our Lord Jesus Christ (the Messiah). Faithful is He Who is calling you [to Himself] and utterly trustworthy, and He will also do it [fulfill His call by hallowing and keeping you]. 1 Thessalonians 5:23-24
