As an aside, let me say that while not everyone is saved by the cross, the work of Christ yields universal or near-universal concrete benefits. Through the death of Christ, the church was born, which led to the preaching of the gospel, and wherever the Gospel is preached there is an increase in virtue and righteousness in society. There is a spillage from the influence of the church, which brings benefits to all men. Also, people around the world have benefited from the church’s commitment to hospitals, orphanages, schools, and so on.
