2 Corinthians 5.16–21

16 So from now on we regard no one from a worldly point of view. Though we once regarded Christ in this way, we do so no longer. 17 Therefore, if anyone is in Christ, the new creation has come: The old has gone, the new is here! 18 All this is from God, who reconciled us to himself through Christ and gave us the ministry of reconciliation: 19 that God was reconciling the world to himself in Christ, not counting people's sins against them. And he has committed to us the message of reconciliation. 20 We are therefore Christ's ambassadors, as though God were making his appeal through us. We implore you on Christ's behalf: Be reconciled to God. 21 God made him who had no sin to be sin for us, so that in him we might become the righteousness of God.

Trust. It is difficult to build, but easy to destroy. It is also the foundation of all good relationships, from families to friends to coworkers. Any betrayal of trust, no matter how small, damages the relationship. Suppose you found out that your best friend borrowed your car without asking and then wrecked it. Even if they repent and you forgive them, your relationship is still not the same as it once was. The bitter aftertaste of guilt and betrayal remains. It takes a great deal of time to rebuild the trust and truly reconcile the friendship again.
When God first created us, the relationship was pure, pristine, and happy. We trusted God, and he trusted us. When we sin, we betray God’s trust. In order to restore the relationship, a high price had to be paid. Jesus shed his blood to erase the stains of guilt and betrayal and to reconcile us to God. Through him, the relationship is restored to the joy of all who experience it.
Unfortunately, too few know the joy of reconciliation that could be theirs. They do not know that all the stains of their past deeds can be cleansed, that the mistakes can be erased, that the old can go and the new can come. That is where we come in. Verse 20 says that we are Christ’s ambassadors, carrying his message of the promise of reconciliation to the whole world. Do you know someone in need of this message of God’s promise? Fulfill your duty as an ambassador: tell them.
