2 Corinthians 5:17-21 – 17 Therefore, if anyone is in Christ, he is a new creation. The old has passed away; behold, the new has come. 18 All this is from God, who through Christ reconciled us to himself and gave us the ministry of reconciliation; 19 that is, in Christ God was reconciling the world to himself, not counting their trespasses against them, and entrusting to us the message of reconciliation. 20 Therefore, we are ambassadors for Christ, God making his appeal through us. We implore you on behalf of Christ, be reconciled to God. 21 For our sake he made him to be sin who knew no sin, so that in him we might become the righteousness of God.
As Christians, we are new creations in Jesus Christ. This means that the sinfulness and selfishness that characterized our life and our speech have been put to death and buried, as Jesus was put to death and buried. And as Jesus has risen, we are now a new, risen creation in Him. We have been set free from and forgiven the sin that once characterized our lives and have been freed to obey in righteousness as a new creation in Christ. We have been reconciled to God and we are now His ambassadors of this reconciliation.
Throughout the New Testament we are reminded of this fact and are urged to live as that new creation. Our forgiveness and renewal does not mean that there are no consequences to our sins here on earth but that we are freed from being punished for them eternally in hell. It isn’t incumbent on others to treat us as new people, although by God’s grace they might, but on us to conduct ourselves as new people. Our renewal in Christ isn’t so that we will forget and ignore the wrong we have done but that it would drive us to a dependence on Jesus Christ with an encouragement that this isn’t who we are anymore.
Being born again in Jesus Christ gives us the freedom to live righteous and holy lives in the power of the Holy Spirit. We are commanded to live this way and true believers in Jesus Christ desire and strive to live this way. They have been renewed and born again not to live and speak as they once did, but to live as ones who have been reconciled to God by the death of His Son. If you are a new creation, live like a new creation. If you are reconciled to God, live as one reconciled to God. If you have been set free to obey in righteousness, then obey in righteousness with the humility and dependence that comes from someone who hasn’t forgotten where they came from and who they once were.
We are new creation ambassadors not because we hide away and forget who we once were but because we show the power of God in bringing us from death to life in how we now live.
