Therefore, if anyone is in Christ, he is a new creation. The old has passed away; behold, the new has come. (2 Co 5:17, ESV)
In the resurrection of Christ something new has begun. It’s not just a rehash of the old. Christ has come as the new Adam. A new creation has begun. In some ways it’s like the old, but in many ways it’s entirely new. Jesus is like the old Adam, but without confusion He is also the God-man. He does not sin; therefore this new creation is without corruption. Christ has done what no man could do. God has raised Him from the dead and has designated Him the living head of the new race. He has become the life-giving Spirit. If you are a Christian you have new life and if you have new life Christ has been raised from the dead. The day will come when the Christian will put off corruption and sin fully and finally. We too will be raised incorruptible because we have already been raised together with Christ. We have been and will be made new.
