'Reconciliation' in the Bible

Not only this, but we also rejoice in God through our Lord Jesus Christ, through whom we have now received this reconciliation.

For if their rejection is the reconciliation of the world, what will their acceptance be but life from the dead?

And all these things are from God who reconciled us to himself through Christ, and who has given us the ministry of reconciliation.

In other words, in Christ God was reconciling the world to himself, not counting people's trespasses against them, and he has given us the message of reconciliation.
