What guarantees the success of evangelism?

‘This view of the atonement guarantees the success of evangelism. God has a people who will be saved infallibly through the preaching of the Gospel. He has chosen them. Christ has died for them. And the Spirit will regenerate them through the message of salvation. This truth kept Paul going in the face of discouragement at Corinth (Acts 18:9–10), and it will keep us going on in our evangelistic efforts today — not only locally, but globally (Rev. 5:9).’
