"Therefore, if anyone is in Christ, he is a new creation; old things have passed away; behold, all things have become new." 2 Corinthians 2:17

As born again believers in Christ we are no longer in unity with the world, but we are in unity -- oneness -- with Christ Jesus. Scripture is clear on this as seen in the following:

"For both He who sanctifies and those who are being sanctified are all of one, for which reason He is not ashamed to call them brethren." Hebrews 2:11

"For you are all sons of God through faith in Christ Jesus.  For all of you who were bapized into Christ Jesus have clothed yourseles with Christ.
There is neither Jew nor Greek, there is neither slave nor free, there is neither male nor female, for you are all one in Christ Jesus."
Galatians 3:26- 28

Our union with Christ is compared to--
The head and the body:
"But speaking the truth in love, we are to grow up in all aspects into Him, who is the head even Christ, from whom the whole body, being fitted and held together by that which every joint supplies, according to the proper working of each individual part, causes the growth of the body for the building up of itself in love." Ephesians 4:15-16

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. He who abides in Me and I in him, bears much fruit; for without Me you can do nothing." John 15:4-5

A building:
"In whom the whole building, being joined together, grows into a holy temple in the Lord, in whom you also are being build together for a habitation of God in the Spirit." Ephesians 2:21-22

Not only are we one with our Lord, but we are in unity with each other.
"So we, being many, are one body in Christ, and individually members of one another." Romans 12:5

Our unity is expressed by oneness of--
Mind:
The Apostle Peter tells us in 1 Peter 3:8-9, "Finally, all of you be of one mind, having compassion for one another, love as brothers, be tenderhearted, be courteous; not returning evil for evil or reviling for reviling, but on the contrary blessing, knowing that you were called to this, that you may inherit a blessing."

Unity of Spirit, as David tells us in Psalm 133:
"Behold, how good and how pleasant it is For brethren to dwell together in unity!" Vs.1 (Read all three verses)

Faith:
Ephesians 4:1-3 gives us an exhortation to unity and in Vs. 4-6 we find the explanation of unity-- "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 all."

Fellowship:
Acts 2:42-47 tells us of the practices of the early Church:
"Now all who believed were together, and had all things in common, and sold their possessions and goods and divided them among all, as anyone had need.
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." Vs. 44-47

Concern:
"That there should be no division in the body, but that the members should have the same care for one another. And if one member suffers , all the members suffer with it, if one member is honored, all the members rejoice with it." 1 Corinthians 12:25-26

Clearly stated we are not our own, but we are God's!
"Or do you not know that your body is a temple of the Holy Spirit who is in you, whom you have from God and that you are not your own? For you have been bought with a price therefore glorify God in your body." 1 Corinthians 6:19-20

Thank you Lord God for making us one with You. Your love is far beyond what man's finite mind can comprehend! We do worship and adore You with hearts filled with the love and joy that only comes from You. Amen
