2Corinthians 5:18
18 Now all these things are from God, who reconciled us to Himself through Christ and gave us the ministry of reconciliation, 19 namely, that God was in Christ reconciling the world to Himself, not counting their trespasses against them, and He has committed to us the word of reconciliation.
20 Therefore, we are ambassadors for Christ, as though God were making an appeal through us; we beg you on behalf of Christ, be reconciled to God.

Well said, and to add to your points, Christ died for our reconciliation, bringing the world an offer of peace with God. In this context, peace means "free of hostilities." As we know, reconciliation takes the cooperation of both parties. I picture it this way. God and man were standing back to back, neither one facing the other, separated, detached, estranged even hostile.
The death of Christ on the cross allowed God to turn and face mankind. Thus, the death of Jesus was for "the whole world", giving the world an opportunity for it to reconcile with God. But in order to be reconciled to God, each man and/or woman, individually in turn, must turn and face God in repentance and contrition.
In the passage above, Paul understands the death of Christ in terms of God, in Christ, reconciling the world to himself. At the same time though, God is working through the apostles, appealing to us that we should around to face him, and make peace with him. Both parties must make peace with each other.
Contrary to St. Anselm, Christ's death on the cross was NOT payment for sins, or even as St. Anselm reasoned, satisfaction of God's honor. No, as Paul wrote, Christ's death on the cross was that one thing, which God would accept, to appease his wrath and bring reconciliation between God and man. Our sins are forgiven, not paid. Grace is offered to those who take the appropriate reconciliatory action: face the truth about myself as a sinner: become aware that God has a grievance; come to fully understand the problem; and take the appropriate actions requisite of reconciliation; conviction, confession, contrition, repentance, and prayer.
