All Christians can (and should!) be thankful that Jesus has made peace between us and God. But what about everyone else?
Jesus offers his peace to all people in every place and in every age. He wants those who do not yet acknowledge him as Lord to accept his peace. But he makes his offer through us, his chosen messengers:
So whoever is in Christ is a new creation: the old things have passed away; behold, new things have come. And all this is from God, who has reconciled us to himself through Christ and given us the ministry of reconciliation, namely, God was reconciling the world to himself in Christ, not counting their trespasses against them and entrusting to us the message of reconciliation. So we are ambassadors for Christ, as if God were appealing through us. We implore you on behalf of Christ, be reconciled to God. For our sake he made him to be sin who did not know sin, so that we might become the righteousness of God in him.
— 2 Corinthians 5:17-21
In addition to making sure that we accept Christ's peace for ourselves, we should extend it to others. This is the mission of evangelization that belongs to every member of the Church: to make known God's love and mercy and bring others into his peace. By sharing the Gospel and helping others enter into a relationship with Christ and his Church, we act as "ambassadors for Christ" and carry out the "ministry of reconciliation."
