Sometimes people say that the doctrines of grace get in the way of evangelism. They say that Calvinism is a detriment when sharing the gospel. However, when approached biblically, the doctrines of grace actually help us share the gospel better in various ways. For one excellent example, here’s what John Murray wrote about evangelism and definite atonement:
“It is often argued that the doctrine of definite or limited atonement is quite foreign and even inimical to the interests of evangelism. For how, it may be plausibly protested, can salvation be freely offered to the lost and its claims pressed upon them if salvation has been procured only for a limited number? Proper analysis of the salvation offered to lost men will show, however, that only on the basis of a definite atonement can full salvation be offered to lost men. True evangelism must ever bear in mind that it is not the mere possibility of salvation, nor simply provision for salvation, that is offered freely in the gospel. It is rather salvation full, perfect, and free. For it is Christ in all the glory of his person as Savior and Redeemer, and in all the perfection of his finished work, who is offered to sinners in the gospel.
This glory and this perfection that reside in Christ as Savior have come to reside in him only by virtue of what he has done in his capacity as the captain of salvation. And what he has done in th is capacity is not that he made the salvation of all men possible, nor that he made provision for the salvation of all, but rather that he wrought and purchased redemption. It is salvation with such completeness and perfection that is presented to lost men in the full, free, and unfettered call of the gospel. But only on the basis of a limited atonement could such salvation and redemption be wrought, and only on the basis of a limited atonement can such salvation be offered.
…If we universalize the extent of the atonement we must limit its efficacy, and when we limit its efficacy it is an impoverished and truncated salvation that the ministers of evangelism have to offer. Just as we mutilate the salvation offered, so do we empty our message of the irresistible appeal that the proclamation of a full and perfect salvation provides. Evangelism thereby not only proves itself unfaithful to the fulness of the gospel, but also robs itself of that which is indispensable to its effectiveness, namely, the recognition on the part of men of the claim, privilege, and opportunity that the full and free offer of Christ entails.
