Summary: When we are in Christ the word of God says that we are a now a new creation.
Therefore, if anyone is in Christ, he is a new creation; old things have passed away; behold, all things have become new.
Anyone who is joined to Christ is a new being, the old is gone, the new has come - GNT
If anyone belongs to Christ, there is a new creation ( the new creation has arrived; or that person has become a new creation ). The old things have gone; ( look, behold ) everything is made new ( the new has come ) - EXB
Therefore if anyone is in Christ ( that is, grafted in, joined to him by faith in him as Savior ) he/she is a new creature ( reborn and renewed by the Holy Spirit ) ; the old things ( the previous moral and spiritual condition ) have passed away. Behold, new things have come ( because spiritual awakening brings a new life ) - AMP
The book of John 3:16 says to us:
For God so loved the world that he gave His only begotten Son, that whoever believes in Him should not perish but have everlasting life.
It all begins with a re-birth, and to have a re - birth we are to fully accept Jesus Christ into our lives as our personal Lord and Savior and by doing this we are joined to Christ and when we are joined to Christ we are now called children of God and this is what been born again means.
Jesus said this to Nicodemus in John 3: 1 - 3
There was a man of the Pharisees named Nicodemus, a ruler of the Jews. This man came to Jesus by night and said to him "Rabbi, we know that you are a teacher come from God, for no one can do these signs that you do unless God is with him. Jesus answered and said to him, "Most assuredly, I say to you, unless one is born again he cannot see the kingdom of God."
Jesus has paid the price for our salvation
Jesus came to set us free from the kingdom of Satan
The death, burial and resurrection of Jesus has given us eternal life
Jesus is the way, the truth and the life - John 14:6
Therefore, if we want the promise of 2 Corinthians 5:17 to be true in our lives we are to be BORN AGAIN! And as long as we are in Christ we are:
- Joined to Christ
- Belong to Christ
- Grafted in Christ
And through this we are called a NEW CREATION
What does this mean?
This means that
1. Everything we have done is forgiven through the blood of Jesus that was shed for us
2. In Christ everything in us becomes new
3. In Christ we are accepted into the kingdom of God
4. In Christ we are his beloved
5. In Christ we have his Spirit - Romans 8:9
6. In Christ we are joint - heirs with him
7. In Christ we have a new life
We are new creations and because of this truth we are able to bear fruits to his glory has we remain in him according to John 15:5 and also in Christ we have now become members of his flesh and of his bones and this is awesome to know that we have Him in us as new creations.
Looking at Galatians 2:20 it says this
I have been crucified with Christ, it is no longer I who live, but Christ lives in me; and the life which I now live in the flesh, I live by faith in the Son of God, who loved me and gave Himself for me.
In Christ we are one spirit with him - 1 Corinthians 6:19
