"Do you not know that your bodies are members of Christ?."
1 Corinthians 6:15
".Do you not know yourselves, that Jesus Christ is in you?
2 Corinthians 13:5

All Believers are in union with Christ!
"For both He who sanctifies and those who are sanctified are all from one Father; for which reason He is not ashamed to call them brethren."
Hebrews 2:11
Let's see what Scripture tells us concerning; this oneness; this unity.

This union with Christ is compared (I will only mention a few)-- To the Head and the body:
"He is also head of the body, the church..." Colossians 1:18

To building:
".Jesus Christ Himself being the chief cornerstone, in whom the whole building, being joined together, grows into a holy temple in the Lord, in whom you also are being built together for a habitation of God in the Spirit." Ephesians 2:21-22

To vine and branches:
"Abide in Me, and I in you. As the branch cannot bear fruit of itself, unless it abides in the vine, neither can you, unless you abide in Me. I am the vine, you are the branches...for without Me you can do nothing."
John 15:4-5

This union is illustrated in the "with Him or with Christ" as we see-- Of being crucified:
"Knowing this, that our old man was crucified with Him, that the body of sin might be done away with..." Romans 6:6

Of being buried:
"Therefore we were buried with Him through baptism into death, that just as Christ was raised from the dead by the glory of the Father, even so we also should walk in newness of life." Romans 6:4

Of being made alive and seating us in the heavenlies:
"(God) even when we were dead in trespasses, made us alive together with Christ (by grace you have been saved). And raised us up together, and made us sit together in the heavenly places in Christ Jesus." Ephesians 2:6

Of suffering and being glorified:
"And if children, then heirs--heirs of God and joint heirs with Christ, if indeed we suffer with Him, that we may also be gloried together."
Romans 8:17

Of reigning:
"If we endure, we shall also reign with Him." 2 Timothy 2:12

This union is MANIFESTED IN oneness --
Of mind:
"For 'Who has known the mind of the Lord that he may instruct Him?' But we have the mind of Christ." 1 Corinthians 2:16 (Also see John 15:15)

Of the Spirit:
"But he who is joined to the Lord is one spirit with Him." 1Corinthians 6:17

In worship:
"The cup of blessing which we bless, is it not the communion of the blood of Christ? The bread which we break, is it not the communion of the body of Christ? For we, being many are one bread and one body; for we all partake of that one bread." 1 Corinthians 10:16-17

And this union is EXPRESSED BY oneness -- Of mind:
" Finally, all of you be of one mind, having compassion for one another, love as brothers, be tenderhearted; be courteous." 1 Peter 3:8

Of faith:
"There is one body and one Spirit, just as you were called in one hope of your calling; one Lord, one faith, one baptism; one God and Father of all, who is above all, and through all, and in you all." Ephesians 4:4-6

Of fellowship:
Acts 2:42-47 tells of the practices of the early church. Vs. 46-47 says, "So continuing daily with one accord in the temple, and breaking bread from house to house, they ate their food with gladness and simplicity of heart, praising God and having favor with all the people. And the Lord added to the church daily those who were being saved."

How wonderful are these words of Paul to the Galatians and to us, "But before faith came, we were kept in custody under the law, being shut up to the faith which was later to be reveled...But now that faith has come, we are no longer under a tutor. For you are all sons of God through faith in Christ Jesus.  For all of you who were baptized into Christ have clothed yourselves with Christ...you are all one in Christ Jesus."
Galatians 3:23-28

No words can adequately express our thanks to You Lord God. What an awesome thing it is to be one in Christ and therefore one with the Father and with the Holy Spirit. We worship, honor and praise You.  Amen
